No graph paper, just a few very vague sketches to get the overall feel, and
then pure povray. The problem with the modelling on this is it used such
intensive CSG that I couldn't have planned it out much on graph paper,
because so many of the shapes depend upon several objects intersecting in
just the right way. So I used good old-fashioned trial and error.

The wheels are just CSG, I take a cylinder, carve out the side with a torus
to get the cross section shape I want. Then the holes between the spokes are
cut out using three painstakingly arranged squashed cylinders (that's 3 for
each hole), they overlap so you just get a smooth hole shape. I considered
using isosurfaces but they'd render too slow for my animation.
