    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.

Looks a bit heavier than the original because I had to slow it down, but it's the same intensity. I would like to make a faster Mandelbrot/Julia set. This is closer to the original effect:

c.width|=0;for(n=200;n-=1/64;x.fillStyle=hsl(${k*22},99%,50%),x.fillRect(n%3*666,n*5,16,16))for(r=C(t*3),i=S(t*4),k=28;--k/r;i=j)j=2*r*i+1-n/99,r=r*r-i*i+1-n%3

Insert backticks where the style changes in that comment, I can't edit it
