Most of it is black metal and 90s/00s idm album cover art 😁

But more seriously, I think it all probably stemmed from a few things.

1. Mindless, repetitive doodling would help me focus during school, boring work meetings, etc.
2. I've always been terrible at answering the question "what should I draw?"
3. I really like detailed, glitchy, grungy, generative computer art; illuminated texts; and pre-Columbian art of the Americas

There wasn't ever a "I want to specifically do this" thought to it. One day I just decided "I'm going to just fill up a page with straight/angular lines" and kind of liked the result, so I just kept doing it and it evolved from there. Here's some super old ones:

Using dots instead of lines at some point:

Here's a couple of styles that I don't really do anymore for no particular reason:

After doing it over and over and over for years I gained more control, built up a repertoire of "patterns"/"structures"/"styles", and could more confidently make "decent" drawings more often that garbage drawings.

But yeah, most of it is just using a small set of simple marks in repetitive ways to slowly build more complex structures, evaluating how it's progressing, and trying to add more without messing it up (or trying to save it). Almost always "intuitive" rather than a conscious decision. The main conscious decisions are essentially:

1. What medium?
2. Angular lines? Drippy, organic shapes? Stippling?
3. Color or no color?
4. Size?

And just wing it from there.
