I was playing around and this came out of the end.

What intrigued me was that it almost looks like it was generated using 
MegaPOV's Post processing facilities, whilst in fact it is pure POV with 
no Post Processing (Other than rescaling and converting to 8bpp .png) 
done to it at all.

I didn't jpeg it since the primary colours came out looking more than a 
tad on the ugly side.

Bye for now,
     Jamie.

        I like it Jamie. The one thing that I notice with it, is the fact
that it seems to get darker towards the bottom right hand side.
     If you could scale this down and make the image larger, I think it
would look like the scales on a butterfly wing. If you could scale it down
enough, it could look like iridescence. Possibly quite useful.
    I also see it in two ways. The first with the blue on top of each cube,
the second with the blue at the base of the cube. In effect, the red and
green swap places when 'seeing' this.

      Very good!

This is probably due to the fact that green on a monitor is very brigth, 
while blue isn't, and on the lower rigth there is a majority of blue.

Looks like the Q-Bert game :-)

That's sort of where I got the idea :)

Or from a screensaver called sproingies which seemed to be heavily 
influenced by Q.Bert anyway.

Maybe if I get bored enough I'll try animating something bouncing down 
it.

Bye for now,
    Jamie.

I think that's an optical illusion due to perspective effects, as you're 
seeing more of the blue illuminated faces in the lower right corner, 
whilst you're seeing more of the green illuminated faces in the upper 
left.

Not really, as all the colour in the scene comes from coloured light 
sources ( rgb <0,0,3.0> for the blue source etc. etc.)

Ta. :)  Like I said, I was playing around and this came out pretty much 
as I expected, except for the pseudo edge detect effect.

Bye for now,
     Jamie.
