My friend found this and I thought it would be handy for a few artists around here. If you have Blender (totally free,
http://www.blender3d.com/), this site has a model to use like one of those posable dolls (I have no idea what those are called --;, the Woodpuppets from Illbleed, you know what I mean)

(file is at the top there)
The only problem is that it isn't bound by human range of movement, so you'll have to use caution. The doll I have has almost zero range of movement, it can't even put its hands on its hips, so it really isn't that useful anyway.
