The award-winning artist Jason Eppink participates in what he sarcastically dubs "an unauthorized, ongoing video-art performance collaboration with the New York City Metropolitan Transit Authority, Clear Channel Communications, and its selected artists." Eppink’s project is the Pixelator, a box of translucent foam-board squares that he mounts over the video billboards that adorn some of New York’s subway entrances. The Pixelator transforms advertisements into 45 quadrants of diffused color, resulting in a more aesthetic urban experience—except, perhaps, for those who coughed up a few hundred grand only to have their ads obscured.
