If you stand at the waterfront anywhere along the Embarcadero, your natural tendency will be to look left, toward our beautiful Golden Gate Bridge. If it’s after sunset, however, look right—at the much-less-fussed-over Bay Bridge that connects San Francisco to Oakland and Berkeley. To celebrate 75 years of connecting San Francisco to the East Bay, artist Leo Villareal was commissioned to cover the bridge with the world’s largest LED-light sculpture, creating a light spectacle that appears to dance on the bridge’s cables. Now a permanent installation, it’s a sight that perfectly showcases San Francisco’s blend of art and technology.
