I just saw a green dot at the end - clever stuff! Talking of being wired up differently, has anyone tried that thing rotating your right ankle clockwise then drawing a figure six in the air with your right hand? Your ankle is then supposed to start turning anticlockwise instead but mine never does.
Cool. I think it depends upon how you draw the 6 if you start at the topit works, if you start in the middle then it doesn't.
