Press w 3 times. It looks like star.

That aside, the Shadertoy repro works, so that's a good starting point.

I'm not correct in this case though. The inadequately sampled function idea would indeed yield these patterns in 1D, but as far as I can tell, in 2D it would yield simple concentric circles centered around origo. Idk, I'll report back when I have a better idea, or I manage to extend the current one to 2D.

@LBPHacker has some damn brains. Good on ya!

I think it's something to do with the TMP or position of the EXOT

like concentric circles with distance between each circle shrinking so that the area between any two adjacent circles is the same. And then put those concentric circles on a square grid. Not sure if this is correct, just a thought

I think it's a moire pattern

Here, have a reproduction of this in Shadertoy: https://www.shadertoy.com/view/tdSfW1 - This doesn't explain it (that's supposed to be the task of my previous comments), it's just cool because it shows the phenomenon in isolation, outside of TPT.

And of course the "frequency" of .tmp (i.e. how quickly layers of EXOT go from bright to dark and back) is a function of distance from origo exactly because EXOT is added with the same rate throughout the simulation, but new layers are distributed over a larger area than previous ones (actually converges to some constant multiple of the distance from origo, much like how the circumference of a circle is a constant multiple of its radius) and are thus "narrower".
