Hey man
a) The scripting isn't too complicated...just a few lines of code which control 2 things.....1 script allows you to drag the ik handle around and stretch the arm that way....the other allows you to set the length of the forearm/upperarm while maintaining proper IK (similar to the stretch you can achieve with the LowMax rig).
b) Sorta......it's kinda weird. If you move the root/chest/clavicle it doesn't appear to stretch at first....but once you grab the IK handle and move
that the stretch "pops" into place. Not necessarily an error/bug....just more of a manual update thing. I'll see if I can't fix the scripts to compensate for that.....
c) I'm using Camtasia for the screen capture
