Saw this on the discovery science channel last night, pretty freakin cool. It's basically a sphere that you can run in, has a wireless virtual reality headpiece and firing trigger. It tracks which way you're running, looking, pointing the gun, etc.

It will be really neat to have stuff like this work well and cheap one day, you could actually play games and get a workout at the same time!
