This is a simple polyrhythm visualizer. Andrew Huang has a great intro to the topic on youtube.

Try speaking his devices to the rhythm of the color changes: "hot cup of tea" over 3:2 or "pass the goddamn butter" over 4:3

Note the double interpretation of the prompt: "intersections" can refer to the colored squares which appear at the intersections of the group of lines or to the way the rhythms intersect with each other.

"Render" exports the animation as a single file with one line per base64-encoded png frame. I use this script to turn that file into a gif.
