The CirculaFloor system uses four robotic tiles that constantly shift position, ensuring that there's always a tile in the direction you're headed. So you would "feel" like you are really walking through a virtual environment.
Meh...I'm not really into the whole VIRTUAL ENVIRONMENT thing but that does look pretty cool. Hopefully they add something to those machines so it speeds up when you do.
That's pretty cool. Well, up until they decide to make another *crag* excercise game using this and never again use the damn thing.
... Well, if they can just make it go a little faster, then you could probably feel more like walking. Hell, maybe if Nintendo decides to use this for something better than excercise and work on it long enough, it could replace the nunchuck.
