    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.

Slightly more interesting depth-sorted spinning tower

I just realised there's literally no reason to do mod 2*pi at the end of the P function, wow
u/Agnes

And there's a map(e=>e) in there! Must have been asleep when I programmed this.
