(becuause i apparently maxed out the last page with K N O W L E D G E)

##logical Operations
Its possible to create the sierpinski triangle through hooking together logical operations. I couldnt find out much more on the specific details for using AND operations. But i did find something to make up for that.
Using molecular assembly with DNA tiles to compute XOR functions, in order to generate a sierpinski triangle. WHAT. THE. HELL. This is some crazy research stuff that intersects molecular biology, cellular automata, and logical operations. In other words, its WAAAY WAAAAAAAAAY over my head, but
=> https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.0020424 the research paper is fun to look and and has pretty pictures.

##Biology
Ive seen two examples of pretty S-triangle like patterns in real life biology.

I asked someone who was knowledgable on the subject of cellular automata for their input on why seashells look like this sometimes, and they generously gave this reply:
"Evidently, there's a row of pigment producing cells along the linear organ that secretes the growing shell at its leading edge, and these cells implement a one-dimensional cellular
automata by having an internal state and exchanging signals with their neighbors. Such cellular automata can often produce Sierpinski patterns. The evolutionary purpose is unclear;
it could be accident, or it could be that the patterns afford some measure of camouflage."

And the other example

This one isnt super suprising, again the S-triangle is a pretty simple construction, so its not unreasonable that simple cell organisms ocasionally stumble upon the structure by chance. Still, its neat to see it actually happen in nature.

##closing remarks
WHEW, I AM BEAT AFTER WRITING THIS. My goal was to create a small compendium of information on the S-Triangle and a lot of places it shows up.
I hope you got some enjoyment out of reading, or just from looking at the pretty ascii pictures, no judgement :)
