It's pretty close already... I think to get closer, you're going to have 
to use some kind of fractal algorithm. Maybe acretion-based, I'm not 
sure. Hmm...

    What a great idea! Didn't think of that! Thanks Andrew. Hmm, ok, so how 
do I start with this idea?

The problem, especially the feathery look, makes me think of some of 
Paul Bourke's experiments:

Yes, that came too to my mind. A pity it is not available for Windows, 
though...

    You're quite right. Thanks Jim. (That page loaded SO much faster than 
when I tried it the other day!)  ;)

    The fifth one down, right-hand side, looks like it would do the job well 
with a longer container cylinder. Maybe Paul will work on a win version one 
day.

Yeah, me too. (I happened to be looking at that page for the first time just
last night.) Some VERY interesting shapes and ideas there.

BTW, here's a (quick-loading!) link to the technical paper he wrote on the
subject.

      Heh, thank you Ken, but I don't need it now that I've joined the BB 
Club...  ;)

     Well, just go for it. I've been having a great time looking at all 
those images that the 'masters' make in places like Highend3D and 3DKingdom 
etc. I couldn't before, (well I could, but I was restricted to only one or 
two viewings that took ten minutes to download), but now, it's just instant.
