I have studied Bill's Code and all the hints he gave with his IRTC entry 2006
last year very carefully. So it is no wonder that I remember it quite well.
Fortunatelly Bill has posted the complete code of his entry and gave a lot of
hints. Many thanks for that to Bill, even after all the years!

IMO his main and wonderful idea is to create an eggshell from a figure and fill
this with a proper media. Having CSG objects every deviation from convexity is a
problem since you cannot simply scale down the figure a small amount to craft
thsi eggshell. This would only work in very convenient situations. With a mesh
you can move the vertices along the normals (Blender seems to able to do this,
but I used Wings for that) and you have an inner object to subtract from the
outer to gain this eggshell soon. Problems arise from vertices which are under
the surface in the original object (joints) or from holes. I remember well
having dived into Poser Jennies nose to close the holes there. Than I learned
about MeshLab and the problem of holes was fixed. So I hadn't to repair the hole
of "the mouth I don't speak with" to cite Till Eulenspiegel. Thanks to Thomas
for mentioning the works of Charles de Coster in another thread here.
I was unaware of his wonderful interpretation of the stuff so far.

But for the picture under discussion here: Really great work. And as ever, a
very good look for details.

Best regards,
Michael
