Tonight marks the opening ceremony of what will become the world’s largest LED light sculpture. With over 25,000 LEDs strung along nearly 5 miles’ worth of vertical suspension cables, the The Bay Lights project, from artist Leo Villareal, will illuminate San Francisco’s Bay Bridge nightly for the next two years.

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.

For The Bay Lights, Villareal developed custom software to generate the glowing patterns and formations that will illuminate the bridge from dusk to midnight. Taking inspiration from patterns found in nature and the Bay’s surrounding environment -- the waves and wind in the San Francisco Bay, the traffic flowing over the bridge -- Villareal’s algorithms will produce unique configurations that will never repeat.
