    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.

bored math test with random

u/Fime

Golfing tip: When calling a random function often you might want to use r={valueOf:Math.random} instead. You then get a new random value when accessing r like a normal variable (no () needed)
u/f8f82804

If you're willing to re-use an already-declared variable you can save a couple more characters: T.valueOf=Math.random
