The Nintendo Wii has a number of bizarre wiimote attachments to make it in to the likes of some maracas, a golf club, tennis racket, steering wheel etc... The latest is an actual controller unit shaped like an American football.
The patent shows a football controller that is designed to assist in a "real-world" football experience. The problem with it is that to get the real-world experience you need to throw it, run in to things and generally have a rough time with the ball... somehow I can't see this happening in a living room where a nice 42" plasma screen sits.
Not sure if this is needed... maybe so... but I still think it's rather dangerous and we could certainly be seeing more cracked TV's when people accidentally let go of the controller.
