If you stand at the waterfront anywhere along the Embarcadero, your natural tendency will be to look left, towards our beautiful Golden Gate Bridge. If it’s after sunset, look right—at the much-less-fussed-over Bay Bridge. To celebrate 75 years of connecting San Francisco to the East Bay, the bridge has been covered with the world’s largest LED light sculpture that appear to dance on the bridge’s cables. Open through March 2015, it’s a sight that perfectly showcases San Francisco’s blend of art and technology.
