I wonder should I restart and rewrite my eschered procedural patterns to 3.5 ?
Is there any person interested ? Any suggestions what should I add ?

Here are old examples of it:

Yes that would be nice. In fact, where might I find the original POV scripts
for this interesting work?

Why do you need to rewrite them? Has the syntax changed in Pov3.5?  Thanks
for experimenting with patterns. I still have stuff to learn from it.  :o)

Somehow not published :-( They were for MegaPOV.

It could be funny to code. I'll check it.

I'll take MegaPOV files if you still have them? Look forward to seeing
the 3.5 version as well.
It strikes me that the bats & angels picture (Circle Limit IV IIRC)
might be a basis for an IRTC:S entry this round, since it basically
compresses an entire "world" into a little circle...
