It can capture your movement in 3D, so you could sit on a couch/chair, etc, and have the camera watch your feet for the imaginary gas/break pedals, or push your arms out to accelerate, and pull them back in to slow down. Keep one hand on the wheel to steer, and use the other to throw an item, in any direction. Using just your hands = extremely limited, using your entire body...not so much. Don't get me wrong, I love Nintendo and the Wii, and I'd love to find some shortfalls of this thing...but they've got some absolutely amazing technology on their hands with this thing.
