Oh yes. Excuse my momentary selfishness.

I used a python script by Ockham: Jiggles

All you need to do is to select the hand, run Jiggles script, analyze then put all MTs to its lowest value "0" and place a multiplier value of .5 or lower like .25 or .1 select the desired morph lets say "grasp" and select down or forward.

It should do a very subtle grasp animation. Try it also on the thumb grasp and spread.

If your animation for example waves his hand. Put the multiplier value to like 5 on the Bend morph so that it will sway with the arm movement.

Passion is anger and love combined. So if it looks angry, give it some love!
