We've had our wii about a month now, and got Zelda: Twilight Princess. I'm addicted. I think Jess likes it in some ways, but she finds the controls cumbersome. I was thinking that perhaps when the reprap is working (yes, using the word "when" instead of "if" is wishful thinking), I could scoop the electronics out of a wiimote and nunchuck and put them back together differently, with a more castaway-ergonomic case. (Well, I wouldn't start there, but that'd be a goal -- I'd probably start with a modified battery door that has bits for the classic controller to clip onto.)
Anyway, wii fun, hacking on wii data also fun.
