Yeah the 'force' movement was really cool. Maybe this is the other way you could do the Jamiroquai video for Virtual Insanuty?

I've never really used VR stuff but I wonder what does it feel like in your head when your legs move and your view moves but your body doesn't?

And then the edge case is extreme but topologically, can something like this work for running where you can lose contact with the ground and your body is sort of compensating for momentum?

I guess treadmills work without people flying off them, so is it just a matter of getting the impulse right?
