Yes (hi Vesa) :
As I make mention in the Planetary Tutorial ...
http://rswiki.matthias-kappenberg.de/index.php/Planetary_Project_Tutorial
Jyrki did get the ball rolling with his volumetric cloud animation
tests using Mark Heuymans shader (someone please correct me if I
have my facts mixed up) .
I did some more work in this area and the 'Mark's Marble'
renderings were a kind of result (below) .

Really should do a tutorial about that whole era of
RS procedural experiments , since they appear to be a
bit forgotten already .

Yeah, more proof that the mailing list is very volatile. Old stuff, June
2005. The main trick was to use a steep curve to map noise turbidity to
itself, to get areas of dense fog and relative clarity instead of a blurry
noise.
I'm using volumetrics routinely. It's slow (maybe problematic for
animations) but despite that: really useful!
For example, I use a gradient fog material, getting a blue-white sky
gradient and volumetric shadows at the same time.
Will be included in the -hopefully upcoming- Wiki tut.
