I just coded lines to be placed in a cool pattern and added sliders that changed it in interesting ways.

I feel like this post lacks technical rigor because the only two people who still post just made turtles analyzing the seeded random functions that they like to use, but the website has "toy" in the name so I probably just overthinking it.
