In celebration of Worldwide Pinhole Photography Day, Simon Lee's Bus Obscura rolls into town, offering free rides and a fresh perspective on our beautiful city by the Bay. Riders on this passenger bus, which has been converted into a mobile, multiple-aperture pinhole camera, can indulge in a unique sensory experience: viewing San Francisco not through the bus windows, but through inverted real-time projections that flow into each other. Accompanied by a specially curated SF-centric soundtrack, the interplay of light and images creates an atmosphere that's simply magical.
