  I used a nice trick to get the light sources to "glow". The idea is not
mine, but unfortunately I can't credit the original author of the idea. I
just read about it somewhere (I really don't remember where). The idea is
simple but very ingenious.

  The camera is not looking at the scene, but in the exact opposite direction.
There's a plane in front of the camera with 100% mirror finish. The plane
has also specular highlighting (with a very small roughness). This simple
trick makes the light sources to "glow".
  Of course it has some side-effects: If you look closely at what the spheres
are reflecting, you'll see that they are reflecting themselves through this
mirror.

  There are just two light sources, those which are glowing.
  The shadows might look a bit odd because the light sources are so close
to the spheres.

: but as a hole: nice pic ... can we expect a higher resolution ???

  There's a 640x480 version at http://iki.fi/warp/pics/

  I can also render a bigger one (eg. 1024x768) if you want.
