They have machines like this at my local gym, but it's in exercise bike form. They have xbox's hooked up to the bikes, and you need to keep the pedalling above a certain rpm otherwise the system shuts off. Genius. But these with the Oculus etc. look fantastic!
It seems "VR" is seeing a bit of a resurgence in the media. Maybe it's because 3D didn't take off as much as they thought...
