In our pilot Midwest issue, I wrote about The Ledge, a new viewing platform at the Sears Tower (now Willis Tower) in Chicago. At the time, only renderings were available of the SOM-designed all-glass cubes that protrude off of the tower’s west face, and the project was expected to open in mid June. Well, it appears that the dizzying new viewing experience is now accepting visitors, as a whole rash of pictures have popped up on flickr. Among them is the above image, which reminds us that sometimes the highest achievement that architecture can aspire to is to fuel the dreams of a child.
