I just recently stumbled upon some videos on youtube of these guys that connected a wii fit balance board to their computer to play games, surf google earth, play warcraft, etc. And from what I know (and have experienced) the balance board is VERY precise is what it does.

Im not sure how, but would it work to incorporate into MT software (as an input device obviously)? Maybe using your hands instead of standing on it?

I dont really know what I am talking about here, just throwing it out there. Any other ideas how we could use this in MT software?

Wow, I really love the idea of surfing over a city!

I guess you could take it apart and use it as a method of monitoring pressure sensitivity. So in a drawing app you could use the force on the acrylic to control the size of the brush. Or in a cooking app, use it to weigh things?!? Looks like a fun thing to play with anyway
