Designed for a friend who lost most of his left arm, Ryan moved the "Z" and "C" buttons from the Nunchuck to the Wiimote. The joystick was separated and can be put on a table, knee, or foot, allowing the player to control it with his or her elbow.
Although Ryan makes his creation look and sound easy, we know the process wasn't simple. Everyone's favorite mod genius, Ben Heck, was so impressed that he featured it as his "Pick of the Wii-k."
