Corpo Elettrico 3.0 - Performed At The Invisible Dog Art Center Brooklym NY (Long Version). People can change the sound through a simple hand gesture. Users can select four kinds of sounds, which can then be modified through hand movements above the table. By opening your hands, you may exit the sound selection and move on to modify another sound. A molecule is placed at the centre of the graphic interface, and every sound is represented by an atom.
 The molecule represents our planet, and the hand gestures represent the modifications made by people. 
Every sound is obtained from the recording of a natural sound, and the users’ hand gestures render this sound more or less artificial. Source
