For the past few years, David Rockwell, that master of stage and scene, has been developing the Imagination Playground, a deployable playground-in-a-box that has been finding its way across the country. Now, he is just finishing a larger playground, sort of a showcase for the concept, at Burling Slip in Lower Manhattan. (As the rendering after the jump shows, it’s quite literally a flagship.) To celebrate the opening of the new playground at the end of July, the Parks Department is taking imagination playgrounds on a pop-up tour, which kicked off this past weekend in Staten Island, with stops in all five boroughs to follow. It truly is a revolutionary concept in recreation, though not the first, as we’ve chronicled. In the current issue of New York, Justin Davidson even gives us the best 19 in the city, yet another mind of the parks renaissance currently taking place in New York.
