Shaping Sounds

Scrapple by Golan Levin. Exploratorium, San Francisco, 2015.

In the computer-operated “Scrapple” system, an overhead video camera registers the positions and shapes of the objects on the table. A projector generates the sliding, glowing bar visible on the surface. Special software links the moving bar with the objects. It also determines what sounds correspond to each shape and runs the sound synthesizer.
