chevthewizard‘s demo of HandMidi, a device that sends MIDI notes depending on how close your hand is to the optical sensor, is pretty cool:

“In this video I’ve used it instead to control the FILTER on a synth in Ableton, and I’m playing the notes on the Korg nanoKey. So as I lift the actual nanoKey into the air the filter opens up on the synth.”

Next time, though, maybe a little more time with the camera on your gear would be in order. 

No – not that gear, you pervs!
