The San Francisco Arts Commission launched its Lights on Market Street project last night, featuring three site-specific installations by internationally-recognized light artists, Jim Campbell, Paul Notzold, and Theodore Watson.

The exhibit, which will be on view until June 2011, is part of SFAC's ArterySF project, which is a series of events, fairs, installations, and performances taking place along Market Street between UN Plaza and the Street.
