Thank you Steve, Setep and Christoph for encouraging me 
to do more of these.

This time I followed Christoph's advice to use change 
texture and use radiosity.

But since I'm not familiar with radiosity settings,
I borrowed some code from a POV-file that Gilles Tran 
posted to povray.text.scene-files back in August:

http://news.povray.org/398EE231.F90E52DC%40inapg.inra.fr

This is my first radiosity image. And my P100 used about
70 minutes to render it.

I have seen nice radiosity images posted by Gilles, Xplo
and Kari, but I'm not able to tell how they differ.

Can anyone please try to explain me what I should look 
for when comparing those images ?

I looks good, the bright parts are a bit overexposed.  The radiosity
settings seem quite good, i suppose you used the same values Gilles used
in his picture.

The main problem about radiosity pictures are of course artefacts, a
strong normal like in your picture often avoids this to some extend.  Have
you had a look at my radiosity tutorial?

I have tried to to use pov radiosity to simulate the actual physical
energy transport process from the virtual environment through monitor
to the viewers eyes, within the limits of pov's capabilities of course.
One key element is missing in those experiments but once I find a way
to get 48bit output from pov expect to see some more tests.

Xplo optimises radiosity quality/render time and Gilles optimises
visual quality :)

Hey, this is cool! I like the radiosity concrete pics, Rivenesque. Interesting
design.

Hi, 

I took the same scene as Tor Olav Kristensen from Gilles Tran
> http://news.povray.org/398EE231.F90E52DC%40inapg.inra.fr

And worked a little bit with it

Nice picture. Another example on how radiosity improves image quality,
though the rendering time price was high.
