    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

u/tomxor

Thanks for all the kind comments :) for those interested: the key is in the parity bit p=i&1 this allowed me to combine two different but similar functions by multiplying parts in an out on each iteration. You should be able to pull the two apart into something more intelligible.

I would love to read a write-up of this some time!
u/BalintCsala

They aren't really complicated, they draw a circle of rectangles with a pseudo random displacement to make it seem more natural. The track is just a bunch of rectangles
u/richev

Maybe not complicated once you understand how it works, but sure seems complicated to me. As @robbyg said, I'd love a detailed write-up.

Shortened by a whopping 55 characters

u/donbright

inspired by @Purpzie #interference i simplified an old one ... what fascinates me is the entire pattern is based on modulo function applied to Quadrance, there is no cosine, sine, trig, or even really commands to draw colors based on posiiton. #waitforit
