The Wave Organ
Created by artist Peter Richards and stonemason George Gonzales, The Wave Organ is a wave-activated sound sculpture made from cemetery stones from the Laurel Hill Cemetery, located at the end of a jetty in the San Francisco Bay. The Organ, completed in 1986, uses 25 PVC organ pipes to interact with waves of the bay; the effects depend on the level of tide, and the Wave Organ sounds best at high tide. The inspiration behind the Wave Organ came from sound recordings made by Bill Fontana, who used a vent pipe from a floating concrete dock in Sydney, Australia to make sounds.
