    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.

Your idea gives really great color to the surface. I wonder if it's possible to animate the colors using your idea, and the wave geometry and lighting using mine.

reduced it by about 15 bytes in case you want to try to do something else with the extra room: c.width|=0;for(i=16;i--;)x.ellipse(1e3+300*S(t+i/9),500+50*C(t+i/9),160*S(-i/2)+160,50*S(i/9)+5,1.6+S(t)/2,9,0,7);x.stroke()
