Light Orchestra by Benjamin James and Ka-Ping Yee

Wave, gesture, or dance to command this 20-foot visual instrument. A small movement creates a flicker; a sweeping motion throws a brilliant fountain of color.

Designed by Ka-Ping Yee and Benjamin James, Light Orchestra uses a Kinect 3-D camera to turn your moves into a shimmering weave of light. The lights are controlled by a particle system: bigger and faster movements generate more and faster particles. Their colors depend on your distance from the camera; select your palette by stepping back and forth.

Light Orchestra awaits your move in the East Gallery every Thursday night from December 3 through January 7.
