Whoa. Quite a change compared to just taking the leftmost point. It looked pretty good in the video, at least as far I can tell by just watching the gameplay.

I'm glad WiimoteGlue offered you a starting point for experimentation. I've been using it to experiment as well, but mostly on the laughably terrible control scheme spectrum (such as playing a Zelda style game with the balance board).
