The Exploratorium presents three major environmental artworks that play off the architecture and the natural elements inherent at the Exploratorium's new site -- works that highlight fog, wind and Pier15's dynamic location at the edge of both the city and Bay. "Fog Bridge" by Japanese interdisciplinary artist Fujiko Nakaya -- known internationally for her ephemeral works of fog. In addition, anarresting, large scale Aeolian Harp by the San Francisco-based artist Doug Hollis straddles a wind tunnel created by Piers 15 and 17, and "plays" the drafts at the opening to San Francisco Bay. Lucky Dragons' DAYLAY is a light and sound installation emanating from an opening the pier above the water. Once the sun sets, the grate will come alive with a programmed light array and a delayed audio recording of what it sounded like exactly 12 hours earlier in that spot.
