The Wave Organ in San Francisco, is a wave-activated acoustic sculpture located on a jetty at the Golden Gate National Recreation Area, 83 Marina Green Dr. The concept was developed by Peter Richards and was installed in collaboration with sculptor and master stone mason George Gonzales. Both men were artists in residence at the Exploratorium in 1986. The inspiration for the piece came from artist Bill Fontana’s recordings made of sounds emanating from a vent pipe of a floating concrete dock in Sydney, Australia.
