today, while working on my lensflare-system, I suddenly had an idea of how to
improve my fastclouds-includefile (which can be found on p.b.s-f): just add some
turbulence and fluffyness, and change the shape of the "cloud container"
slightly.  This is the result.  Not photo-realistic, but I think it might be
usefull in some cases.

rendertime: 16s on an Athlon XP 2500+

Looks kind of like an oil painting

I've seen real clouds looking similar to those. Just add some landscape and you're
done :)

then I should continue working on my landscape-generator.  lensflares, clouds,
landscapes... maybe I should quit my job and do this fulltime instead :p

(if only that were possible :))
