Are you a creative coder? A computer-savvy musician? Do you use Processing? PureData? MaxMSP? VVVV? OpenFrameworks or even Cinder? Have you heard of the OpenSoundControl library and the possibility it offers to send data over the local area network between devices?
This app gives you the opportunity to experiment with the state data (understand "surface data") extracted from its user interaction. Super easily, over the Wifi and at UDP protocol speed (that means fast!).
