I've found a neat technique to pixellate almost any object in povray. I have
uploaded the AVI to http://www.uio.no/~simenkv/pixeltorus2.avi for those
interested to see. (Couldn't find a way to fit it under the limit.) It's a
1.2MB download, so beware ... It's just a spinning pixellated torus; decide
for yourselves.

I have great plans for this one!

Simen.

That is a very neat special effect. Do you plan on sharing it? I'd like to see
how that was done

Nice effect. Is there a way to set the resolution?
I'm curious how you did it (I can think of ways for a torus, but since
you claim you can do it with almost any object...)
It isn't an isosurface, is it?

Wild guess...(meaning the way I would do it)
You are using MegaPOV. You have a loop or more likely nested loops which 
go through each possible cube position. At each point, you use the 
eval_pattern() function with the object pattern to find if the point is 
inside or outside the object. If it is inside, you place a cube at that 
position.

Not-so-wild-guess, I'd say. Just that I used standard POV for it. I've
implemented it as a macro, so there are virually no ends to the
possibilities. I'm developing it, with different textures and so forth.
