goes slow return quick.
it took me too long to complete beside the Houdini bugs :-) .

I would like to know how you would rig this simple periodic movement.
If some one can give tricks and tips of how to handle better the chops.

for example i had to use pose-bland 4 times, couldn't replicate a mirror of the motion.or edit it the way i wanted .
This kind of tip would be very useful for me and others if some one wants to share his\her ideas.
