Neat grid pattern.

I like this one.
It seems like you're getting pretty good at this.

I do too, which is why I posted it.
It brought to mind the vintage Corelle plate rim pattern. (attached)

I'm getting a bit better at finding interesting patterns and translating them
from other languages/syntaxes.
I still have a devil of a time with some of them.
Some I can't get to work at all, especially if I have to make lines, use x and y
at the same time, or try to make a parametric function based on atan2(y, x).
I'm also trying to figure out why sometimes I only get a partial pattern.
But they _are_ more than formless grayscale vomit, so there is definitely some
progress.
When I understand WHY things work or don't, and know enough to fix them, then I
will be lots better.
When I can invent such functions on my own, then I will be good.
But that was half of the goal of this - to try implementing so many functions
that eventually I found changes that worked, and could be applied to others that
failed, and iteratively get better.
I'm almost at 200 functions, and at some point I'll have (temporarily) run out
of patterns to copy, and can start investigating variations and combinations.
There also seems to be various common methods for making patterns, and perhaps I
can distill them all down into several macros to make rendering each method a
little easier.
Thank you as always for your interest, tutelage, and encouragement. :)

This one's sort of like dice.
mod (floor(x)+floor(y), 2) somehow is NOT the same as even (floor(x)+floor(y))
IIRC, Bill Pokorny mentioned something about how floor isn't quite "right".
anyway, this is the last one for the night.

IICRC... Rings a bell.
With yuqk, I do remember changing the code which creates the 0-1 ramp
wave - in official POV-Ray there is some hard coded magic which
sometimes causes trouble if one hits the right (wrong) values.
There is too some hard code clamping of values coming from functions
into the pattern mechanism that I removed. However, this bit, from your
results, I would say you are already avoiding. (That you are limiting
your function() values into the pattern mechanism to 0-1 or >0.0 ranges)

It moves.
There are colour spots popping everywhere.
It shakes.
