    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.

What is this even meant to be?
u/PiggyClone205

A word game thing in which you list numbers, and say fizz on every multiple of three, buzz on every multiple of five, and on every multiple of both three and five, you say fizzbuzz.
