Thanks. Sure thing, just let me clean up some dependencies. Be warned,
I'm pretty sure there is at least one flaw in my math so far, since a
couple of those solids are protruding from their spheres.

Thanks.
I tried using the solids Paul Bourke posted at
http://local.wasp.uwa.edu.au/~pbourke/geometry/platonic/
But I can't seem to get the proportions or position right.

No prob. On cursory examination of those I couldn't work out whether
the edge length or radius is uniform, but I didn't do any calculating.
I cheated and just made the shapes for mine in Wings, mainly because it
was a quicker way to get the type of hollowing I wanted, and copied the
edge length of each into the include file for the calculations. The
spheres/shapes having non-zero thick walls made things more complicated.
However, something still must be wrong, or they wouldn't protrude like
that.
