Rune Spaans' Super Simple Rig v1.2

Rune Spaans has released a new version of his free rigging system designed to make it easier to work on animated projects. The updated version brings some great improvements: new FK/IK arm and legs (stretchable and have bendy controls, with soft IK), stretchy head and spine, angle sliders on all rotations, ability to resize the rig locator height interactively, a simple function to cut up your mesh into a proxy object, etc. Also of note, the author has been working on a pro version of the rig, which will offer some extra features, including comprehensive face rigging tools. More information and download link for v1.2 of the script can be found on MUForums.
