Leap Motion(https://www.leapmotion.com/) Myo(https://www.thalmic.com/myo/) Sorry, these are all I could think of. I know there was this startup in Silicon Valley that did something with gesture based music control and I think they got acquired by Microsoft, but I cannot recall their name right now...sorry.

I figured it out, if anybody else cares: http://socialprintstudio.com/
