TouchTool is a multitouch music synthesizer and visualizer that “looks like Twitter.”

Using Snow Leopard, a MacBook’s multitouch trackpad, Quartz composer, OSC and Chuck, it can track up to 11 fingers, make independently synthesized sounds for each touch and display it in a nice view of birds and clouds, so your visual brain can relax while your musical brain tries to process the distorted noise it makes

TouchTool was created as part of Music Hackday Berlin.
