"Calder" Interactive art by Zack Booth Simpson

One in a series of interactive artworks using rear-projected IR tracking (patent pending)created by Zack Booth Simpson & Mine-Control in 2004. Partcipants draw forms which are reinterpreted as Calder-esque mobiles. Holding the mobile allows them to gently move in 3D and finally fall to the ground when unsupported. Shown at SIGGRAPH 2004.
