    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.

Very nice! I made a golfed version: x.fillStyle=R(b=250,100,b);x.fillRect(b*4,1079,1,1);x.drawImage(c,10*S(t),t<6?t-10:t-.01)
