Prismatic pyramid evokes desert mirage by day, Aurora Borealis by night.

Given that their pyramidal acrylic installation at this summer's Burning Man was inspired in part by Pink Floyd's Dark Side of the Moon album cover, it seems safe to say that the architects at Red Deer "get" the festival's vibe. "We try to get very intimate with our sites, so it was interesting to approach one that we hadn't been able to visit," said founding director Ciarán O'Brien. "Some of the primal forces we could see at play there were the heat of the desert and the way people interact with structures. Specifically, for us it was about light in all its forms." The UK firm worked closely with the structural engineers at Structure Mode to design a transparent six-meter-tall structure comprising interlocking equilateral triangles, while New York Institute of Technology professor Charles Matz contributed an integrated light display based on the Aurora Borealis. "All kinds of imagery came to mind that held to the desert landscape," said O'Brien. "By day, the concept evoked a mirage; by night, a kaleidoscope. One is ephemeral, a non-place; the other is specific, a beacon." Called Luz 2.0, the Burning Man installation is only the latest iteration of an ongoing exploration of the relationship between matter and light. The project began as a response to a commission for a band pavilion. "Red Deer's original idea was a scaffolding framework that would be clad in some reflective material," recalled Structure Mode's Geoff Morrow. "We suggested going one step beyond that and building an acrylic pyramid, to make it much more special." The clients canceled, but the designers applied for grants, ran a successful Kickstarter campaign, and debuted Luz at Secret Garden Party 2013 in Abbots Ripton, England. The first Luz featured a touch-sensitive floor screen-printed with a colorful pattern that appeared to change shape under different lighting conditions. For Burning Man, Red Deer omitted the floor "so that you interacted with the playa landscape," said O'Brien. Red Deer and Structure Mode jointly developed Luz 2.0's reciprocal modular system. "It was really interesting investigating how all these different connections could work, what different shapes could work within a three-sided pyramid," said Red Deer's Lucas Che Tizard. "The system we use is composed of equilateral triangles, but it actually gives us more than just pyramids—you see hexagons as well." The architects worked first with hand sketches, then transferred their ideas to SketchUp before moving to 3ds Max, Rhino, and Vectorworks to finalize the structure and start to explore how the modules would connect to one another. Structure Mode analyzed the design's structural stability in Oasys' GSA Suite.

Red Deer flattened the final design and emailed the files to the CNC cutters. At that point the three-dimensional installation "became a flat pack kit," said O'Brien. "Part of the challenge was that each of these pieces should be human-sized, so that they could be built by a small team using basic tools in desert conditions." To simplify installation, Structure Mode developed a streamlined bolt-and-nut assembly based on furniture-making connections. "In a way it's kind of low-tech, but it looks high-tech," said O'Brien. The UK contingent shipped Luz 2.0 to the Nevada desert in three crates. The components took longer than expected to arrive: though they had hoped to begin installation on Monday, the architects were forced to wait until Thursday. Nonetheless, the on-site crew managed to assemble the pyramid in just two days using hand drills. Matz's team, meanwhile, arrived on site with the electronics, including custom hardware based on 3D models sent to them by Red Deer. The installation of the lighting system "came together seamlessly," said O'Brien. "We were somewhat concerned about voltage, but it worked out." The only disappointment involved the Mogees sensors, designed to trigger changes in the light show as visitors climbed on and around the pyramid. They worked well in a small-scale test, but "unfortunately the settings didn't translate to the seven-meter structure," said O'Brien. "I can't say it fully fulfilled that brief." Red Deer and their collaborators will soon have another shot at realizing the vision behind Luz 2.0. As befits the installation's emphasis on the immaterial—not to mention the ethos of Burning Man itself—the architects plan to re-erect the structure elsewhere. "We've had quite a few offers from various benefactors, but we haven't figured out what would be best," said O'Brien. "Right now it's in storage in Reno, awaiting its next move."

Forget about the Sharknado, New York–based designers at SOFTlab have created a vortex of flowers that has taken over one Manhattan shoe store, bringing SOFTlab's signature parametric forms to the modern shoe brand, Melissa. The Soho store already grabbed design headlines when it opened its flagship location decked out in a custom-fabricated Corian interior by architecture firm Eight and Associated Fabrication. This latest design intervention is part of Melissa's "We Are Flowers" campaign that used organic shapes and colors to inform its shoe line. SOFTlab was the chief designer behind “We Are Flowers” and, as the title suggests, created a looming art installation of synthetic flowers right inside the Melissa flagship. Using bright colors and familiar natural forms, the installation creates an aesthetic meant to appeal to both shoppers and pedestrians just passing by. And with 20,000 distinct flowers, it's difficult to miss. The installation, as it happens, is an encompassing, immersive one that hangs over the top of the store in its entirety. This is achieved by suspending the flowery panel from a hand-bent metal frame. The underlying digitally-designed mylar structure that supports the flowers is comprised of fastened, laser-cut pieces that give the final product its curving shape. The flowers are also laser cut and individually hand-fastened to the delicate netting. The process is detailed in the installation video above. The final product is a gleaming interior garden at Melissa that winds its way through the entire store. The We Are Flowers installation is currently on view at Melissa's Manhattan flagship at 102 Greene Street.

Composite materials are on display in the undergraduate-built FIBERwave PAVILION.

Carbon fiber’s unique properties would seem to make it an ideal building product. Untreated, carbon fiber cloth is flexible and easy to cut. After an epoxy cure, it is as hard as steel. But while the automobile and aerospace industries have made widespread use of the material, it has gone virtually untouched by the architectural profession. Alphonso Peluso and his undergraduate students at the IIT College of Architecture set out to change that with their FIBERwave PAVILION, a parametric, sea life-inspired installation built entirely of carbon fiber. "We want to make the studio an expert resource for people trying to get into carbon fiber in terms of architecture," said Peluso, whose students designed, funded, and built the pavilion this spring. "There’s a studio in Germany that’s in their second year of working with carbon fiber, but I don’t think anyone in the United States is working with it." Peluso’s studio began with an internal competition. Because the spring semester course followed a class dedicated to the exploration of various composite materials, many of the students were already familiar with the pros and cons of carbon fiber. "Toward the end of the first semester we started working with carbon fiber, and it wasn’t the greatest result," said Peluso. "But we knew we had to keep working with it. That played a big part in the selection of the design for the second semester." The students judged the submissions on constructability as well as aesthetics, he explained. "It was interesting to see the students as the pavilions were being presented, see their minds turning on: ‘Okay, this one is feasible—this is one we can actually build.’ Sometimes the design was a little better, but the overall project seemed less possible within the time frame." The winning design is based on a bivalve shell structure. The student who came up with the idea used parametric design software to explore tessellations of the single shell form. "What I was pushing them to do in the first semester was large surfaces that weren’t repetitive," said Peluso. "In the second semester, it was like they intuitively knew there had to be repetition of the unit." As a group, the class further developed the design in Rhino and Grasshopper. But while the students used parametric software to generate the shell pattern, in general FIBERwave PAVILION was "less about designing in the computer," said Peluso. "Most of it was fabrication based." The studio was hands-on from the beginning, when students were asked to submit a small-scale carbon fiber with their competition entries. They went back to Rhino to make the molds. "We had to make six molds," explained Peluso. "Even though it was one identical shell unit we had to produce 86 of these shells. When you make a composite unit, if you have one mold you can only make one shell per day." In the end, the students fabricated a total of 90 shells (including several extra to make up for any defects) over the course of about four weeks.

• Designers IIT School of Architecture CARBON_Lab

"The actual assembly was pretty quick, the pavilion itself went together in less than a day," said Peluso. Laterally, bolts through CNC-drilled holes connect the shells at two points on either side. The overlapping rows of shells are secured vertically through bolted pin connections. The installation remained on the IIT campus for one month, after which the students disassembled it in just 25 minutes. The Chicago Composite Initiative, which provided crucial technical guidance during the project, has since erected FIBERwave PAVILION in one of its classrooms. The fundraising component of the project was as important as its design and fabrication elements. Peluso initially hoped that the carbon fiber industry would donate materials, but "we didn’t have as much luck as we anticipated because we hadn’t done anything before that would warrant their interest," he said. "That’s one of the goals of the pavilion itself, to create an awareness in architecture that this could be a great material to use." Peluso’s course did have help from West System Epoxy, which provided the curing resin at a discount. To fill the funding gap, the students ran a successful Kickstarter campaign, raising $6,937 from a $6,500 goal. They made incentives for the donors, including 3D-printed necklaces and earrings. "I don’t think we realized how much work was going to go into that," said Peluso. To raise additional funds, the class held bake sales on campus. For Peluso, the process of designing and building FIBERwave PAVILION proved as valuable as the finished product. "The way the students collaborated made the project a success," he said. "Sometimes in group projects you get a few drifters, and some really strong ones. But all twelve students really stepped up. This wouldn’t have happened if they hadn’t all come together as a group."

Barcelona-based artist Jaume Plensa said the first thing he does after checking into his hotel during stays in Chicago is drop by Crown Fountain, the digital waterwork that features human faces spitting water, just to make sure his popular downtown installation really exists. “Sometimes I think it was just a beautiful dream I had 10 years ago,” Plensa said at a press conference Tuesday. Millennium Park, which turns ten years old in 2014, counts Plensa’s whimsical fountains among its more popular installations. A new piece of his, on loan from the artist through the end of 2015, attempts to build on that momentum. Entitled 1004 Portraits, the new installation features three cast-iron heads some 20–23 feet tall, their tranquil expressions facing west toward Crown Fountain and Michigan Avenue. Walk around the visages, though, and their volume drops away—the figures, all portraits of young girls with their eyes closed, are warped and stretched along their vertical axes. Their names are Laura, Paula, and Ines. A fourth head—this one 39 feet tall, bleach-white, and made of resin—watches over the entrance of Millennium Park at Madison Street and Michigan Avenue. That piece is entitled, Look Into My Dreams, Awilda. (The other 1,000 portraits referenced in Plensa's title refer to the LED projections that cycle through as the backdrop for Crown Fountain.) “I invite everyone in Chicago to dream with me and with my heads in Millennium Park,” said Plensa.

An interactive installation reconsiders the definitions of enclosure and openness.

Warren Techentin Architecture’s digitally-designed La Cage Aux Folles, on display at Materials & Applications in Los Angeles through August, was inspired by a decidedly analog precedent: the yurt. “Yurts are circular,” explained Techentin, who studied the building type as part of his thesis work at Harvard’s Graduate School of Design. “That began the idea of using small-diameter rods and taking software and configuring sweeps with some special scripts that we found online.” But while the yurt’s primary function is shelter, Techentin’s open-air installation, built of 6,409 linear feet of steel pipe, is a literal and intellectual playground, its form an investigation of the dualities of inside and out, enclosure and openness. Once the architects became familiar with the scripts, which allowed them to manipulate multiple pipes simultaneously, they found it easy to generate designs. The hard part was settling on a final shape. Then an off-hand observation narrowed their focus. “Somebody made a comment about, it looks like a crazy cage,” said Techentin. “We realized, ‘Oh, there’s this cage component. What if we imagine spaces inside spaces?’ That’s where these interiorized conditions came through, kind of creating layers of inside and outside.” Technical constraints further influenced the form. “We had to jump out of the digital world and decide how this was made in reality,” said Techentin. To minimize materials costs, the architects decided to work with schedule 40 steel tube, which is available in 24-foot lengths. Returning to Rhino, they broke apart their model and rescripted it accordingly. They modified their model again after learning what radiuses their metalworking contractor could accommodate. “It was kind of a balancing act between hitting these radiuses, the 24-foot lengths, and repetition—but how do you get difference and variety,” said Techentin.

Warren Techentin Architecture originally sought a digital fabricator for the project. But the quotes they received were too high, and they could not locate a manufacturer able to work with pipes longer than six feet. They contacted Paramount Roll and Forming, who rolled and bent the tubes by hand for one-tenth of what digital fabrication would have cost. “It wasn’t what we wanted, but in the end we wanted to see the project through,” said Techentin. Paramount sent the shaped steel to Ramirez Ironworks, where volunteers interested in metalworking helped assemble the structure. The design and fabrication team then disassembled it, painted the components, and transported them for reassembly on the site, a small courtyard in the Silver Lake neighborhood. La Cage Aux Folles invites active exploration. “My work draws great influence [from] architecture as something that you interface with, interact with—that envelops you, becomes part of an environment you participate with,” said Techentin, who overheard someone at the opening call his structure “a constructivist playground.” “We fully intended people walking around in there, lying down,” he said. “The surprise factor were the number of people who feel inspired to climb to the second and, more ambitiously, the third cages. We’re not encouraging it, but people do it.”

June brought good weather to Cleveland, and those who rang in summer with a visit to the Cleveland Public Library encountered an airy installation of white frames and threads crisscrossing the Eastman Reading Garden. It’s not the first piece of public art to active the space outside the Cleveland Public Library. Last year a giant reading nest designed by LAND Studio and New York artist Mark Reigelman took wing in the library’s Eastman Reading Garden. This year’s piece, by X. studio founder Ivan Juarez, is the fifth installation in the library’s “See Also” public art program, which is organized with help from local designers LAND Studio. The program is funded through an endowment established by Lockwood Thompson, a former library trustee and art collector. Juarez will use almost 15,000 feet of rope before the piece comes down at the end of October. Dubbed Drawing Lines, the installation aims to help visitors “discover new spaces, shadows and frames” in the garden, per a press release from the Cleveland Public Library:

“A continuous thread will move across new and existing elements in the garden to filter the natural light and create new passages and spaces to gather and reflect. At the same time, the installation’s architecture is being broken apart. Its walls are transparent.”

LAND Studio is also engaged in a makeover of Cleveland's downtown Public Square and a rails-to-trails project along Cleveland's old RTA Red Line.

Hedge Two-Way Mirror Walkabout Metropolitan Museum of Art 1000 5th Avenue, New York Through November 2. 2014 One of the great gifts bestowed on New York in the summer is the Metropolitan Museum of Art’s roof garden. You are thrust into Olmsted’s Central Park from a promontory surrounded by the perimeter skyline on all sides. The trick with the rooftop art commissions is to play with the space, the views, and the interrelationships between the two. The goal is to make the viewer see them differently—you want to feel like the rooftop is your personal terrace in the sky while sharing it with others in a magnificent secret shared space. Dan Graham’s Hedge Two-Way Mirror Walkabout plays with what he calls this “leftover space” of rooftop by framing the viewer's “elliptical experience” with various man-made and natural elements: glass, steel, stone, hedgerows, chairs, and ForeverLawn (definitely not AstroTurf). Stepping from the fake grass that covers the rooftop—green mixed with yellow and brown in different blade thicknesses—one climbs almost imperceptibly onto a slightly-raised platform of granite slabs that forms a square. These pavers support a sinuous bisecting slab of steel-trimmed, S-shaped, mirrored glass, a staple of modern skyscrapers, that is supported on the east and west sides by hedges, that, as Graham noted, demarcate property lines. If you enter from the north side, you can gaze through the glass barrier to those on other side and to Central Park South beyond. When you approach from the south side, you are struck by the reflections of the skyline behind. It’s a concave/convex funhouse, where one is constantly catching glimpses oneself. Graham has been working with “pavilions” for a long time, and Hedge Two-Way Mirror Walkabout feels like a more rural version of his much-missed Rooftop Urban Park Project (1991) atop the Dia Center for the Arts on West 22nd Street. You want to sit on the lawn and have a picnic. At the Met, Graham worked with Swiss landscape architect Günther Vogt, who also designed the stainless steel moveable chairs with recycled rubber coating manufactured by Burri. On the museum’s second floor are related projects by Graham which attest to his long-standing interest in architecture and public space. A 20-minute video called Two-Way Mirror Cylinder inside Cube and a Video Salon (1992), commissioned by Dia, investigates atria, shopping arcades, and winter gardens, both historical and contemporary ranging from the Crystal Palace, Galleria Vittorio Emanuele, the Ford Foundation, Citicorp Park Avenue Atrium, Charles deGaul airport,  Parc de La Villette, World Financial Center’s Winter Garden, and the IBM Building. Graham narrates, as he does in Two-Way Mirror Hedge Labyrinth (1991), a short video centered on a pavilion installed at a private home in La Jolla, CA, where he muses on the city—how landscape architecture redefines it, how the labyrinth is a metaphor for it, and how two-way mirrored glass’ transparency and reflectivity mimics it. Graham’s concerns with movement and time, human interplay and asymmetrical procession, all take place on a mirrored stage.

Soto: The Houston Penetrable Museum of Fine Arts, Houston 1001 Bissonnet Through September 1, 2014 The final installation in Jesús Rafael Soto’s Penetrables series—Houston Penetrable—will be on view at The Museum of Fine Arts, Houston, as of May 8. An interactive display of 24,000 PVC tubes, each hand painted and tied, will hang from the second story of the museum’s Cullinan Hall. The strands’ collective visual expression is of a floating yellow orb visible upon a transparent background. The installation’s kinetic quality defies the idea that viewers look only with their eyes. The interaction of museum visitors playing with and among the strands is, in fact, the final element that completes Soto’s work. The installation, which took almost a decade to finish, is one of the few that Soto created for the indoors. The piece will be accompanied by a neighboring exhibition of eight other pieces that exemplify the artist’s career, including Plexiglas boxes, and selections from his Agujas (Needles), Vibraciones (Vibrations), and Ambivalencias (Ambivalences) series.

James Carpenter, the world-renowned architect who has left his mark on projects like New York City's Millennium Tower, Brooklyn Bridge Park, and others, recently revealed his latest work, Light Veil, at Dallas’ Cotton Bowl Stadium. The Cotton Bowl Public Art Project, a $25.5 million endeavor aimed at revamping the stadium, included a contest that Carpenter won out for equipping the stadium with a new facade. Carpenter’s design relies on the sole use of hanging mesh ribbons whose delicate strength elicits an ethereal effect. The facade is constructed out of uniformly spaced thin mesh ribbons, 2 feet wide and 50 feet long, that weigh in at a slight 80 pounds. Up close, the strong parallel lines impress with their connotations of durability, reliability, and uprising power—positive associate qualities for any sports stadium. From a distance, however, the impact is wholly different yet just as impressive. The ribbon’s interact with natural sunlight to create a shimmering front, hence the aptly named Light Veil. Some writers have dubbed Carpenter’s treatment as “gift-wrapped.”  The phrase keys into the fact that the design’s simple elegance delivers a surprise no matter which way you turn. Carpenter’s work delights in the interplay between light and glass, and could be considered a signature trait of his work. “The brighter a material gets, the more solid it feels,” Carpenter has said, thereby highlighting the underlying paradox of the Cotton Bowl’s new face: how basic structural elements solidify the intangible in a very real way. The Cotton Bowl Project included adding more club seats, concession stands, and general clean up.  The veil, which cost $8 million to complete and comes third or fourth in a trend of mesh facades, allows the audience to more fully experience the interplay between the sporting event, the stadium’s interior, and the city beyond.

Last year, a vacant lot across the street from the Pulitzer Foundation in St. Louis became the site of a design competition for a temporary built-environment installation. New York’s Freecell Architecture won PXSTL's $50,000 project budget and $10,000 honorarium for a proposal to erect an adjustable canopy for performances and gatherings—an idea Kristina Van Dyke, director of the Pulitzer Foundation, called “both monumental and ephemeral at the same time.” Freecell’s installation, entitled Lots, opens Friday, May 9. An opening celebration from 7:00 to 9:00p.m. will include a dance performance by students at the Grand Center Arts Academy, which will be connected to the Mildred Lane Kemper Art Museum by free shuttle bus for the evening. Through October 5, Lots will occupy the space across Washington Avenue from the Pulitzer Foundation, an elegant concrete building designed by Tadao Ando. (Read AN’s Q&A with Tadao Ando here.) Public programs will take over the canopy throughout the summer, funded by grants from the foundation. Thirteen grant recipients will provide programming for the inaugural PXSTL installation. See PXSTL's website for more information about the opening event, which is also sponsored by the Sam Fox School of Design & Visual Arts at Washington University.

The latest installation at Silver Lake gallery Materials & Applications, Warren Techentin's La Cage Aux Folles, truly brought out the inner monkey in Los Angeles' architecture community this weekend. The cage-like structure is made of a vast series of curved structural steel tubes, which simultaneously rigidify the piece and create unique spaces in and around it. They also, it turns out, created an ideal climbing apparatus for partygoers at its opening this Saturday, who got to know every square inch of the 17-foot-tall construction. One ambitious young explorer actually got stuck in the center of the piece and had to get fished out by an experienced climber. "It was free performance art for everybody," joked Techentin, who said he never anticipated visitors climbing so aggressively on the piece. He added that the form was originally inspired by the small structural members of yurts that he saw on a trip to Mongolia, slowly becoming something much more abstract. La Cage is open until August 29, and next month will host a series of interactive performances.

A room-filling parametric design makes its way from the classroom to Austin's famous music festival.

When Kory Bieg and his students at The University of Texas at Austin School of Architecture began working on Caret 6, they had no idea that it would wind up at this year’s South by Southwest (SXSW) music and arts festival. But the rippling, room-filling installation soon took on a life of its own. Within months, Bieg’s undergraduates—who had little previous exposure to digital design—had designed and fabricated Caret 6, and assembled and disassembled it twice, first at the TEX-FAB SKIN: Digital Assemblies Symposium in February, and then at Austin’s most famous annual gathering in March. Caret 6 developed out of a research studio taught by Bieg, who is also associate director of the regional digital fabrication and parametric design network TEX-FAB. Selected to chair TEX-FAB’s annual design competition, Bieg knew that he would soon face a problem: how to display the winning entry in a gallery much larger than it. He put his students to work on a solution. “The idea was to create a kind of counterpoint to the winning entry. [We] needed to fill space,” said Bieg. At the same time, the studio would teach the fundamentals of digital fabrication. “It was really just an experimental exploration of what these tools could produce,” he said. Caret 6’s white and grey diamond-shaped cells cascade from a central catenary vault with three column bases. Two secondary vaults project from either side. The front face of the structure flows down to the floor. “The idea is, we didn’t actually know who the winner [of TEX-FAB: SKIN] would be,” said Bieg. “We wanted to design a ground surface that was modular so that we could replace some of the cells with bases for their models.” The 17 students enrolled in Bieg’s course first created individual study models of aggregations and weavings amenable to digital fabrication. In an internal competition, they narrowed the field to three. Bieg broke the studio into teams, each of which experimented with creating volumetric versions of the designs. In a departure from typical parametric installations, Bieg and his students decided to stay away from patterns that gradually expand and contrast. “Our interest was not [in] doing subtlety, but local variations that are quite abrupt, like going from a large cell to a small cell,” said Bieg. “So part of that was a result of the way we structured it. Instead of aggregating cells, we designed a series of ribs.” The primary ribs form the vaults’ seams, while the secondary and tertiary ribs divide the structure into asymmetrical pockets. Halfway through the semester, Bieg called Alpolic Materials, whose Aluminum Composite Material (ACM)—a thin polyethylene core sandwiched between two sheets of aluminum—he had worked with on an earlier project. Alpolic agreed to donate supplies for Caret 6, “so we refined the design according to the material we had,” said Bieg. He also drafted students from UT engineering to calibrate the structure’s thickness, scale, and cantilever distances. “It kind of just evolved from these different processes coming in,” said Bieg.

• Fabricator Kory Bieg and UTSOA Design Studio V
• Designers Kory Bieg and UTSOA Design Studio V
• Location Austin, Texas
• Date of Completion February 2014
• Material Alpolic Materials ACM, polypropylene, high-density polyethylene, binder clips, bolts, o-rings
• Process Grasshopper, Kangaroo, 3ds Max, CNC milling, manual assembly

Back in the studio, Bieg’s students used 3ds Max for form studies and Kangaroo, a Grasshopper plug-in, to fit the tessellated diamond pattern to the vaults. They also used Grasshopper to develop an assembly system of binder rings, bolts, and o-rings. Bieg and his team fabricated the installation using UT’s CNC mill. They cut the vault pieces out of Alpolic ACM. The elements closest to the floor are polypropylene, while the intermediary pieces are high-density polyethylene. The students assembled and disassembled Caret 6 manually. At first, they tried working with a QR-code system, scanning each component to determine its location. When this took too long, they projected a digital model of the form on a screen, then called out each piece by number. For SXSW, where they had only six hours for assembly, they subdivided the structure into sections that could be quickly recombined on site. Caret 6 travels to Houston in September, where it will rejoin the entire TEX-FAB: SKIN show. But while the installation has already moved beyond its original context, Bieg insists that it remains rooted in the SKIN competition brief, which focused on building envelopes leveraging metal fabrication systems. “[Caret 6 is] not really a program per se, but more of an experiment about the same concepts that were part of the exhibits at TEX-FAB,” he said.
