For the World Expo 2010 in Shanghai, ART+COM created an impressive installation that reflects a facet of mobility: an array of 100 white prosthetic hands each holding a small mirror and each rotating on its axis. The installation has become a crowd puller in trade fairs and conferences all over the world.
The mirrors reflect a floodlight’s beam onto the wall across from them. At first, the points of light move about chaotically; then, they coalesce into the shape of the Chinese character meaning “mobility.” All the prosthetic hands in this spatial installation were manufactured at the production facilities of Otto Bock, a leading developer and manufacturer of state-of-the-art prostheses.
Each hand is attached to an individually controllable stepper motor, which makes it possible to smoothly control the movement of the points of light.
