    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.

cut down a bit

More cutting, and vertical centering: c.width|=0;x.translate(960,540);for(q=20;q--;x.fillRect(a=-50*q,a,b=99*q,b))x.fillStyle=R(x.rotate(t/3),255-12*q) (113/140)
