There are all sorts of strange controller accessories for the Wii. We have things like guns, NERF accessories, and the Wii Balance Board. You might recall that patent application that turned up in August 2009 for a football accessory for the Wii.
The finished product has turned up now and it is made from material similar to NERF balls. The Wii remote snaps into the holder on the bottom of the ball and is hollow with a grip to let you grab hold of the controller.
The thing should be a cool accessory for those who like to play Madden and other football games. The big difference between this football controller and the patent app drawing from last summer is that the finished product has no place for the Nunchuck to sit.
