Elbows which have 2 bending points won't look like broken soda straws. This is a skeleton for James. In order to fit within the skin, and stay there, the knee has to work like this, with bone crunching bone: If the knee had two joints, the bones could act like real bones with a nice tidy patella fronting them. (Note that I don't use precanned poses, or limits, but with 3 1/2 years of life drawing as well as rock climbing and dancing, I have a fair idea of how the human body moves.) Carolly
