  Thanks Andy (and all), but as Hugo said, your is also very well done, and 
has some things better. I also like specially your focal blur, mine is 
somewhat strange and does not seem to follow the camera zoom.

  png "hf_bolt"

  water_level 0.1
  translate -.5
  scale <1.3,.1,1.3>
  translate <0,.27,0>
 }
}

  The height_field is the nice lettering on the top (which of course says 
"POV-RAY"), and is done with The Gimp, puting white letters in circle on 
black background and blurring it a bit.

  There are also some facts about the image I forgot to mention:

  + To get the feeling from Brazil, I used a double CD from Joao Gilberto.

  + The image uses Kari rad settings from the cornell box scene, with the 
count lowered a bit.

  + The focal blur uses Warp recommendation of variance 0.

  + The metal texture uses an averaged normal (only the normal) from 4 
patterns at diferent scales, and a "procedural" image_map "a la Tran".

  + The light is created with my new macro, wich uses basically 
fade_distance 1 fade_power 2 and the light color is multiplied by a very 
high value (about 3600 for this one). 

  + Render time was 7h... !

  I promise to release the light macro this weekend, mainly because I want 
some feedback about all my (surely wrong) assumptions creating it.

  Bye...
