No, I did not use macro from /scenes/advanced/cats/coolcat.inc.
It is pure csg, and we can not get 100% smothness with csg like this - we
have at join line continuous surface, continuous normal vector but
discontinuous derivative of normal - so, we receive smooth surface if no
reflection, but unsmooth if there is reflection. I think, with csg we can
not solve this problem.
 And if you really like checkered plane, I can post one (even imagine:
Subject: checkered plane. Attached picture - checkered plane ;) It was
joke...

 Sincerely Yours, Alex Kluchikov.

 I used something like envionment map - a textured hollow sphere, big enough
to contain all the scene, with no_shadow and no_image attributes set. I
already answered on similar question asked by Tek - see. May be, it would
be better to post sources?

 Sincerely Yours, Alex Kluchikov.

Could you post the source for that bozo pigment? it looks really good.

OK. Look in p.b.s.-f. in a few minutes.

Very nice, Alex.  I used a similar method to make solder-flow in electronic
devices- a torus subtracted from a cylinder.  Check out the attached image.  And
once again, very nice image.


Cheers!

Once again, it's a really nice image! It's obvious that you have a lot of 
fun with POV. Thank you for posting it in p.b.s-f. I'm playing with it 
now...Just like all the other sources that you gave us in the past week... 
Your talented, don't stop!!!

Ciao!

Nice. Another interesting CSG can be found in
http://news.povray.org/povray.binaries.images/12039/
with cross section how toruses played with each other.

I backed up and looked at some of your previous posts. It is nice to see
someone putting some effort into creating something other than endless
retreads of the same old kitsch. I am looking forward to seeing more.
