Look over the shoulders of ocean explorers as they map and send their ROV into the little-known and unknown regions of the deep sea. "Voyages of Discovery" connects the Exploratorium with NOAA's newest ship, the Okeanos Explorer, currently in the Pacific Ocean near Indonesia, as it carries out its first exploration voyage.

The Wave Organ is a wave-activated sound sculpture located at the end of a jetty in the San Francisco Bay. It was created by artist Peter Richards and master stonemason George Gonzalez in 1986.

The installation is an unlikely sight: a collection of curbstones and cemetery stones that appear in the Bay like an ancient ruin or a strange dream. In this unusual place of discovery and contemplation, the musical phenomenon is only part of the point.

In this audio slideshow, Peter Richards, now a senior artist at the Exploratorium, shares his inspiration for creating this piece and explores its function as a theater in which many different kinds of human experiences unfold.
