Well, ASL (spilling beans) requires finger animation. Can't be done correctly without it. I have only included the body parts inclusive to the motion (arms, hands, fingers). So, this may have some beneficence. But there are many times when the hands/fingers touch each other or other parts of the body which ends up with fingers and hands doing 'psychic surgery'. :) ockham, these definitely fall under categories 2 and 3.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
