'Bubbles' is a multi-user installation made by Wolfgang Muench and Furukawa Kiyoshi for Lovebytes Festival 2002. Viewers can interact with a real-time simulation of floating bubbles. When you enter the light beam of the video projector your body throws a shadow onto the projection screen, the bubbles bounce off your shadow float around, collide, burst and make music.

The screen area is captured by a video input system and each bubble is able to independently recognise both the shadows' touch and its direction. Defined as autonomous objects, the bubbles' behaviour and their response to any user-interaction follows a set of simulated physical laws. Both the overall state of the complex system and the shadows' interaction with the bubbles create non-linear musical structures, that are generated in real-time utilising a midi interface and midi synthesiser.
