Leo Villareal's "The Bay Lights" project on the San Francisco Bay Bridge will illuminate the infamously foggy bay with 25,000 LED lights, making it the largest LED light sculpture in the world.The lights illuminate in an organic pattern, taking inspiration from the waves, the pervasive wind and the ebb and flow of car traffic coming from the East Bay over to the City. The algorithm has been programmed to never repeat itself, and will be visible from dusk until midnight for two years following its installation. Villareal, who recently exhibited two high-profile public art installations in NYC—Madison Sq. Park’s Buckyball and the Bleecker Street subway station’s Hive—is known as an LED artist, and has been working in the medium of light sculpture since the late 1990s.
