This is amazing and kinda what I have wanted to do for a long time. I want to combine the motion leap with the oculus rift for board games. Imagine everyone sitting around a table with the headsets playing Twilight Imperium, you'd see everyone as the alien race they are. You'd have a floating galaxy in front of you, and you could simply motion out what you want to do. This works all kinds of magic for so many board games and reduces all the fiddly nature of the pieces, setup, clean up, etc. Just play.
Before I switched back to hardware synths I was staring to mess with a Leap driving Sensomusic Usine, and it works fantastically, very smooth, natural tracking of about 20 points in each hand on a modest laptop.
