all comments are welcomed :) version with dispersion is rendering now (12 h 
on Athlon 1,7 and only 50% yet)

And here comes nicer version (19h on Athlon 1,7), loosless-compresion 
version is at http://raf256.com/006.png

Did you forget photons for the metal ring before? Or did you switch from
regular caustics to photons for the second? That first one isn't any good
compared with the other which looks very good. Maybe the ripples seen in the
shadows aren't right but that makes it look better to me, like some
distortion in the glass might cause.

I really like that landscape. Kind of makes me think of wet crumpled
notebook paper, in a remote way of course.

Oh yeah, and your not using antialiasing yet for these since they are only
test renders I suppose. I actually didn't notice that when first looking.

Thanks :) It's due to dispersion, and better spacing of photons

Yes.. it's a bug in my scene :/ I'm not shure will decreasing spacing help 
with it, and shurly it will slow down render even more.

2 * noise3d (small and bigger) + large noise * distance (for big bumps at 
top of image)

Yeep... if this version took 19h, then +focal-blur +radiosity +AA it would 
take... oh my god ;) I should convince my friends to run POV for my in 
night :)

Could try it with 'jitter' then, if you haven't already.
