    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.

Basic reduction to 140 (a little bit different in the beginning):q=1.57/~~t;with(x)for(c.width^=beginPath(),i=108;i--;)lineTo(o=(960+C(v=i*q+t/q)*440),840+S(v)*99,l=20,l),lineTo(o,240+S(v)*99,l,l),stroke()
