    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.

c.width=b=1920,x.rotate(.8) for(i=400;i--;)z=(e=50)*S(i*t/8)+i*e,x.fillRect(z,-b,e,1e5),x.fillRect(0,-b+z,1e5,e) - 112... Now you can fit in a fillStyle() :D
