Check this out. With only 3 finger, it can:

1. Throw: Kim Clijsters has a new sparring partner !
2. Dribble
3. Pen spinning
4. Knotting a rope
5. Taking a rice-grain with a pincet
6. Regrasping.

Amazing !

And all this with tactile control in milliseconds. Imagine 2 hands of 5 fingers, or 10 hands of 7 fingers for the matter.
