    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.

Changing the callback to "x.fillStyle=hsl(${d++*25},50%,50%)" turns it into an abstract art generator :)
u/yonatan

swapping PI/2 for PI/5*6 gets you pentagrams :)
