| This is large wave-activated 
              sculpture located at the end of a jetty a short walk from the Exploratorium. 
              A wonderful collection of granite building material that existed 
              on the site was used as the construction material for the sculpture. 
              The different length PVC listening pipes extend from the seating 
              areas to the water. The intensity and complexity of the wave music 
              is directly related to the tides and weather. |   |
