@hover I just pushed it.
@weightt_an gave me a expression. I don’t know what his wx, and wy stands for, but I got something unique and happy with it, and that what matters when it comes to generative art. He is also why I added dx, and dy as accessible variable for my Thorn Fractal filter.

Here’s a totally not-useful-at-all thing I did a while back:
rep_multiplicative_persistence:
num=$1
init_num={('$1')-48}
v_num=$init_num
persistence=1
do
($v_num)
repeat w#-1
if $>==0 n=1 fi
m={$n*i(#-1,$>)}
n=$m
done
rm.
num=$n
echo $num
v_num={('$num')-48}
if $num<10 break fi
persistence+=1
while (!$num<10)&&(!isin(0,$v_num))
echo $persistence

I got the inspiration from a numberphile video where Matt Parker has done a python code to do this.
Seems relevant to image processing.
Whoa, whoa, it is? How?
It is just a vague notion but don’t we generally want to approach certain values and results? At some point of the looping and refinement, the change delta is irreducible. Then the job of an algorithm is done.
In context of image processing, results should at least have some variability in it. I’ll admit, I had not explored what it can be used for, but I do know that it has low variability. I could however make a multiplicative persistence version of prime spiral, that is a idea.
I was speaking broadly. I don’t know the specific applications in your specific case. I still want to point out that variability is coded in or represented by the math: it is by deliberate design.
Ghastly. Will give someone nightmares. 
Really? I thought it looks like it can pass for embodiment of feminity and beauty. It does look ghastly with Deuteranopia.
I understand now that I see the face. Reminds me of the Persona (series) - Wikipedia JRPG. The characters in the game use manifestations of their psyche to battle evil.
After watching this video - https://www.youtube.com/watch?v=LhZVBK1ehE0
I went along with the string used there.
Presenting 3d Lyapunov Fractal. Not sure how to make great renders with Blender as that’s not my specialty, but this’ll do.
This is something I want 3D Printed and cast within resin now coming to think of it.
@grosgood @David_Tschumperle Thank you so much for the help!
Here’s an animation:

@Reptorian - very satisfying filter. Impressed with the amount of research and work you’ve put into this. 
Here’s something made with Rainbowify filter:

Another Popcorn Fractal. This time it’s different than the regular version.
I attempted to color in the Complexion Burst image

awesome
Wasn’t able to comment on your latest image right away. On small screen mobile, it didn’t look interesting but on the laptop the textures are kind of feathery. Maybe a hint of something you could do in the feature…
