Controlling VSTi with hand gestures ala theramin

A year or so back I remember coming across a video of a person controlling HSO articulations/cc1 events via hand gestures done over a some sort of receiver upon the desktop. My searches to find the video again and figure out what the controller was have not yielded results. Anyone remember it or know what the controller is called?

Just after posting I changed my search to gesture cubase air and found the controller. IC Air and Leap Motion. Here’s a link in case anyone else ever looks for it:

All the way back to 2013! Found the demo video. IF you have never seen it in action its worth the watch super cool. he is playing and gesturing at the same time but I expect you could use two hands even if wanted to manipulate prerecord tracks.
