Summer in Long Island City has become synonymous with MoMA PS1's Warm Up series and in turn, those evenings of drinking and dancing to DJs in PS1's courtyard have become an annual showcase for the latest in architectural experiments by young designers. This year's entry is a pale-blue sea anemone of a structure with a name usually associated with fast food. But this spiky cerulean wonder not only chills hot summertime crowds with fans and cooling mists of water, its stretched-fabric shell is impregnated with special nanoparticles that supposedly filter pollutants from the surrounding air.
