Contributed by Sharon Butler / Diana Cooper’s new public art project “Double Take” is rich with art historical references and playful wit, breathing life into an otherwise unsightly ventilator shaft installed opposite the egress from the Roosevelt Island subway tunnel, where it blocks a magnificent view of the city across the East River. The mosaic, crafted in collaboration with glass artists in Italy, incorporates fractured and twisted linear perspective to create the illusion of roiling depth, blurring the boundary between static skyscrapers and the roaring East River.
