    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.

Blimey!

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.
