Everything is sped up 3x (the system runs at 10fps, but this video is 30fps). There's a quick dance at the beginning, then experiments with different capture settings. The random Rubik's cubes were to help with calibration. That's me at 1:02.
The next issue I'm going to address is the sine distortion. The webcam-projector sync needs some more work, too.
