   Well, fortunately POV-Ray media scattering type 2 takes care of all
that... what I'm really looking for is some method to create convincing
cumulus shapes. Right now they are just a bunch of blob spheres filling
a random conical shape, but I've got some ideas to try from this paper:

   I will try to start with a base blob with just a few big components
and then trace a lot of smaller ones on the surface of it.
