A frisbee is an interesting idea. Another is to make the Wii Wheel into a sort of player-held avatar of the in-game object they're controlling, and using the tilt, distance, and pointer controls to control that object's position in space. That could be used for pretty much anything from a 3D Marble Madness equivalent to a flight sim where you literally are holding the spacecraft in your hands instead of a control stick for it.
Sky Render - Sanity is for the weak.
