vibration-based musical instrument that finally puts those years of air drumming to use. It's a small, piezo-based MIDI controller that lets you turn pretty much any surface into a musical instrument. The device has a built-in suction cup, comes with velcro straps and plugs into your computer's microphone port. The fun really starts with the dedicated controller software, that converts your percussive punches to your virtual instrument of choice. You're not limited to drums either, as you can map your taps to a velocity sensitive melodic generator to create musical tones and scales. Luckily you won't have to sit on your hands to get one of these either, as the Pulse Surface Controller System is available now for $59, or you can tap-tap-tap the video after the break for a demo.
