This is what I want for my next video game controller. Actually, that's not strictly true. I'd be perfectly happy with an interface that is slaved to my actual body movements through motion sensors. Obviously, I'd need a special place to use it (it's hard to jump kick or swing a pretend sword at your desk). But it would be super if I could get a workout while playing video games. I hate the claustrophobic nature of most console controllers. I prefer mice and keyboard over the thumb-rending XBox/PS2 controllers.
