I learned backward kinematics using Moray years ago. If you can correctly 
define the origin of the rotation points of each movable robotic element, 
you could probably achieve that *fairly easily* in POV-Ray, or am I missing 
something? It is *just* a matter of correctly nesting and translating, and 
defining the rotation angles and constrains. It is a lot of tedious work, to 
be sure, though.

I usually end up with scenes taking 72 hours or more to render. It does not 
matter to me. I usually build in a lot of switches in order to test more 
rapidly though.

Great image by the way. I love your robot.
