A modder has made a Wii Nunchuk mod. It was designed for a good friend of the modder, who's arm only extends a little below the elbow. The design for the Nunchuk is intended to be used at the elbow with the joystick resting on a knee. The two buttons from the Nunchuk were removed and placed on the side of the Wii-remote where they can be easily pressed with the middle and index fingers.
