Experiments in Motion met HWKN’s Wendy this weekend in all her spiky blue glory. Perched on MoMA PS1’s outside wall and straddling the museum’s two outdoor spaces, Wendy is an ecologically conscious festival of moving parts. The blue fabric that comprises the starburst, so designed to maximize surface area, was sprayed with titanium nano particles that attract pollutants in the surrounding air. As the air is filtered, each of the water features - cascading pools, misting spikes and water jets - clean the fabric by carrying the pollutants to the ground. The giant fans located within the starburst keep the air in constant circulation, sending clean air back into the community and filtering the incoming air. The ostensibly still Wendy is actually a frenzy of motion and an installation you definitely don’t want to miss.
