ROFL im still looking for the one where i dont need to use my hands.....
no seriously, if youre looking for something like that, they have things that graphic designers use where they can freehand right onto their compters; and laptops have the touchpads, which in essence dont click. and i believe i have seen larger versions of those touchpads for sale in those tech-gadget-magazines that they put in the back of airplane seats. unfortunately i dont have any cool links or anything to throw out. : (
