Ned Kahn is an environmental artist and sculptor, famous in particular for museum exhibits he has built for the Exploratorium in San Francisco. His works usually involves capturing an invisible aspect of nature and making it visible; examples include building facades that move in waves in response to wind; indoor tornadoes and vortices made of fog, steam, or fire; a transparent sphere containing water and sand which, when spun, erodes a beach-like ripple pattern into the sand surface. In 2003 Kahn collaborated with Koning Eizenberg Architecture, Inc. on a piece for the Children's Museum of Pittsburgh consisting of hundreds of movable flaps that respond to the wind creating visible patterns. Kahn won a MacArthur Foundation "genius grant" fellowship in 2003, and the National Design Award for environmental design in 2005.
Kahn lives and works in California.
