It's great. A few complaints though.
1) Glutes look like hips.
2) I use the scroll wheel instead of clicking and i have to scroll a lot with this lua. It would be nice if you had a version for scroll wheel users with clicking is relax/hold and scroll wheel is contract/extend.
3) If possible make it work in multiplayer.
(Following were already mentioned)
4) It looks wierd with no body so if you could add that it would look much better.
5) Also a suggestion: make it so it tells you if you are dismembered or fractured.

Unfortunately, Lua has no way to tell if a limb is dismembered of fractured at this point. I assume hampa will add it in the future, though right now it isn't possible. (Maybe in 2.7?)
Also, neat. You're good with programming geometry and drawing,...I suck at those... ._.
