Space.py script has been upgraded to include the useOrient attribute. When the useOrient attribute is switched to On, the transform maintains it's own orientation. I personally use it often to animate shrugs as seen in the gif below.
The only controls animated are the clavicle controls. The right side (red controls), have orient space turned off and hence the arm continues with regular forward kinematics. The left side (blue controls), have orient space turned off which means the arm keeps its 45 degree angle with the body.
As of now, there is only one item left in Piper's to do list! Afterwards I'll finally start animating and move on to what this blog is really supposed to be about, game development.
