Nintendo are known for unique and original methods of controlling games, from pioneering shoulder buttons to their recent pulse monitor, and a recent patent application for a cushion with a pocket for holding a Wii remote while the user holds an attached nunchuk looks like it could possibly continue this trend. The idea is that the user can tilt back and forth on said cushion while using the nunchuk in unison to control a horse (or possibly another animal).
According to Nintendo, "For centuries throughout the world, horseback riding has captured the imagination of adventurous people". So there you have it. Forget shaking a stick to make a man fly through space, or attempting to do an uncomfortably large amount of pushups on a board, the real adventure is riding a cushion with a pocket.
