Have you seen the controller for Nintendo's next generation console? The system is tentatively titled the Nintendo Revolution. The controller, which is comes in two pieces, does a fairly good job of living up to the title.

Check out this demo ad and, if you're a geek and you haven't already seen it, get ready to pick your jaw up off the carpet. The controller has a motion detector allowing it to serve as everything from a ping pong paddle to a samurai sword.

I can't see myself ever bouncing around my living room while fighting on-screen ninjas. Since when have exercise and video games gone hand in hand (Dance Dance Revolution doesn't count)?

Innovation or insanity? Both? Have a look and decide for yourself.
