The clouds were produced by a macro I derived from one I found on the newsgroups
here.
Unfurtunately I cannot refind it and cannot remember the author to give credit.
It calls a macro, AddCloud
repeatedly which produces media within a box container combining a spherical and
boxed density.  I added emission and absorption values which is how I got the
dramatic illumination of the distance clouds.

The sun combines a glow and a disc
