    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.

Now combine this with d/2416

Needs heavy golfing: c.style.boxShadow=inset 0 ${r=Math.random()*2}px 10em #642;c.style.filter=contrast(.5)brightness(${r/99+.9})sepia(89%;c.width=192+r;for(i=9;i--;x.fillRect(r*90,0,.01,108))x.fillRect(40+i*10+S(t)*30,40,5,20)

Partial attempt: d/11106
