Space Tension and the Airbender: two air gesture controllers

Saw this yesterday:

which is a lot like my Space Tension/Qi project I have been developing since 2007.

I reached out to the guy, and he was aware of my work. While they seem to do the same thing, they go about it in quite different ways. His tracks objects, mine tracks movement. Both transfer what they track into MIDI information to control synths and make music. Looking forward to some interesting conversations!
