Today MoMA PS1 announced the winner of their 13th annual Young Architects Program (YAP), in which an up-and-coming design company is picked to transform the museum's courtyard during the summer. This year's winner is HWKN (Matthias Hollwich and Marc Kushner); their installation is called Wendy and will double as a sort of air filter to cancel out motor vehicle pollution. If you're a fan of PS1's popular Saturday dance parties, here's a look at where you'll be partying this summer.

PS1 describes Wendy as "an experiment that tests how far the boundaries of architecture can expand to create ecological and social effect. Wendy is composed of nylon fabric treated with a ground breaking titania nanoparticle spray to neutralize airborne pollutants. During the summer of 2012, Wendy will clean the air to an equivalent of taking 260 cars off the road." The structure features "spiky arms made of the nylon fabric" and "will reach out with micro-programs like blasts of cool air, music, water cannons and mists to create social zones throughout the courtyard."

Curator Pedro Gadanho calls the design "iconic, but with a twist. By combining off-the-shelf materials and scaffolding systems with the latest cry in nanotechnology it is able to produce both an out-of-the-box ecological statement and a bold architectural gesture." And as long as the nanoparticles don't multiply into a mutant, flesh-eating swarm of nanorobots, it should be a fun summer! Here's a look back at some of the previous Warm Up installations.
