    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.

neat! a little smaller: c.width=99;for(i=2e2;i--;)for(j=0;j<C(t*i*j)*50;j++)x.fillStyle=R(255-55*i,255-25*j,3,1),x.fillRect(j*5,i*5,5,5)

You've reached the end.
