I mentioned this here already:

But I thought I'd share it properly as its own thread. I saw Francois Labreque's
"short code" style signature and was inspired to make my own.

Mine's a lot more clumsy and is too long for the signature feature on the
povray.org web interface. But I like it :-)

Great! Now, I HAVE to render it and find out what's what:}

Have Fun!

Damn.   This is second only to Warp's ridiculously obfuscated signature.

Well done.

I haven't had the time to sit, focus, and reverse-engineer it, but this is very
cool!

I accidently render it at 600 by 100 and it looked better!
It's real funky how did you come with IT?

Have fun!

BE, spoiler warning if you still want to reverse-engineer it...! :-)

I took the literal signature I already use in my pre-existing brand 
imagery (visible at https://petermarkley.com and on various social 
profiles), and decided to recreate it as a mosaic using tiles of 
POV-Ray's granite texture.

I rendered a huge image of the granite texture and "vibe-coded" an 
OpenCV Python script that matched pieces of it to pieces of the 
reference image by visual similarity. This Python script gave me a list 
of these texture-space coordinates, ordered by source tile.

 From there it was a matter of encoding the coordinates in a way that 
was both compact and easily readable in POV-Ray. That's why in the code 
there's 8 lines of dense random ASCII strings. Then for each tile, the 
POV-Ray scene finds and decodes its texture-space coordinates, and 
translates the granite texture to that point.

The result reminds me of a Magna-Doodle when you look at them up close, 
because of the grainy pigment splotches separated into cells.

Ha ha!
That would be like reversing pov-ray's turbulence algorithm.

You're a total psychopath.
And you completely belong here. :D

I greatly look forward to seeing more of the graphic expression of your mental
illness, and hope to be inspired and learn a great deal from your participation
in our little esoteric corner of the internet.
