Moving some of my old Vimeo videos over here
This tool streamlines the process of creating deformable controls that were demonstrated by Pixar in one of their demos. It should work for pretty much any rig.
It's a technique I learned from Wasim Khan
Harry Houghton had also made a video tutorial outlining the process (https://vimeo.com/94663329)
The rig is called Morpheus and was created by Josh Burton(http://www.joshburton.com/projects/morpheus.asp)
