You have boxes instead of cylinders there ;)

I think the original also has boxes, allthough it is not 92.6% sure. The
scan is bad and full of  JPEG artifactas...

Yes, I think it's difficult to see if they're boxes or cylinders in the
original image. It's easy to change though. See the attached image. (I
also corrected the perspective a bit more.)

Yeah, I've got some POV-Ray experience, but I never could figure how to 
to get media to do what I wanted, and I figured media would be the best 
way to do this image.

I actually tried to make it, but again, I can't quite figure out media, 
so it never worked.

Actually, its the original source that is bad and full of MPEG 
artifacts.  At first I was going to post a PNG file of the picture, but 
it was 500k, and the JPEG is only 27k but looks no worse.

This looks very very nice.  It would have taken me well over a week of 
experimentation to do what you did in under 6 hours.

Though I think the long lines of blue should be a little bit thicker.

It's actualy very easy,
just add

interior { media { emission .6 } }

in my image full texture is:

#declare Mat2 = material {
  #if (QQ_MEDIA=0) texture { pigment { color  <.6,.8,.97> filter .5 } finish { ambient
.5 }  }
  #else
    texture { pigment { rgbf 1 } finish { ambient 0 diffuse 0 } }
    interior {
      media {
        #local C=<.3,.72,.99>;
        density { cylindrical color_map {[0 rgb 0*C][.5 rgb .3*C][.8 rgb .7*C][1 rgb
1*C]} }
        emission .6
      }
    }
  #end
}

and full .pov file is in .scene-files

Well, it's post-processed with some blurring. I also "cheated" with the
blue lines. In the original they have the same thickness no matter if
they are close to or far away from the camera, so I did nearly the same
with my lines. (They are actually cones, not cylinders!) But it seems to
give the right effect...

Done. Attached.

I haven't played with media much myself either.  I'm finding it interesting
playing with Rafal 'Raf256' Maj's code.  Rune if you aren't using his code
could you post yours as well.  I think I'd find it interestings seeing how
two people coded this its you did it any differently.

Thanks,
Carl

Hmm...the lines closer up look thicker, but the lines farther away just 
look brighter.

Also, I need it in 1024x768.
