That looks good, very smooth! Though the orientation of the hands seems to 
just come from the arm orientation.

I keep thinking about doing my own system, but first I'd have to convince 
myself that I can make a decent looking character that renders quick enough 
to be used in animation, and I can just never be bothered!

It would be cool if you published the code, I wouldn't use it directly, but 
I'd definitely use it for reference if I ever get round to writing my own 
one.
