Thank you Stephen, yes a magnifying would show the trees but I think it would be
a bit disturbing to the scene.

First I played with Rune's particle system to find a believable ground flow. If
one finds the correct position and size of the emitter object it is fine to find
the general direction of flows. But it has its limitations since the particles
interact only with the mountain in this case and not with each other. Then I
created ten layers of the cloud using the particles and for each cloud ist
predecessors as the ground object in a modified version of Gilles Tran's
makecloud2 macro (mainly allowing for different directions and using a gaussian
distribution than his uniform). For his tomography I grouped them into four
groups at the moment. The resulting df3-files were used as different media in
the same box. Rendering time is now some 5 hours.

I don't think it very critical. I plan to work a little bit on the colors and
the densities. May be I
change the grouping of the clouds.
