At least, for me it is...I can't figure out how I did it.
Enquiring minds want to know, because I really like the
glows around the spheres.  I did use 3.1g to make it, but
lost the original in a system crash, and the one I redid
just doesn't have the glows, no matter what I do...I *do*
know that I wasn't using anything terribly special, just
one or another settings in the finishes and/or radiosity.

Looks like you have some type of light source at each ball.  Maybe each ball is half
solid on the top and half transparent on the
bottom with a light source inside.

The balls are all homogenously textured.  Am not certain as to if a
light source is at each ball, since I attempted to use do that last
night and it didn't look the same...

Looks to me like the bottom two spheres could be closer to the camera,
therefore darker to the viewer, but the light source underneath the
two spheres are at their origin?

 I know I'm totally wrong with the above, so is the main lightsource
emanating from the top sphere only?

  Or is it a mixture of the two?

  Nice image though.   :)

I seem to remember that Pov 3.1 had an "issue" with it's radiosity, so that
if you rendered with radiosity in a scene with  purely black background, the
radiosity could come out *way* too strong. I had a few scenes of mine
explode like that, and the glow in your scene looks *exactly* like the
radiosity problem I remember.

It's fixed in 3.5, whatever the problem was.

But I *like* the glow. :P

Couldn't you just give your objects an ambient finish?
With radiosity enabled, that makes them emit light.
