    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.

Can reduce this down to 118 w/ with(x)fillStyle=hsl(${t*40%360},100%,50%),beginPath(),arc(t*1e4%1920,0,100,0,7),fill(),drawImage(c,0,0,1920,1123.2)
