    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.

You should really make the rectangle blue or something.

the "rectangle" is actually an emoji, I know its a water drop because I can see it on my newer PC
u/Lazy1337

well not really the strict definition of "emoji" but you got it.

Basically a UTF to binary decoder. The variable z is the zoom level.
