    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.

Impressive! I like the c.width|=M=Math hack. Apparently Math is evaluated to NaN in the process.

you can do M.sqrt() with ES6 power operator as **.5 should yield a net gain of 2 chars

Oh right! I haven't gotten used to it yet since I'm on Fx51, which doesn't seem to support ** yet. Thanks!

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()

u/Woodmouth

Ohh, if you wait long enough it goes grey, but then if you wait even longer, it quite suddenly goes back to color, and then suddenly even more grey

After that it ends up resting on a kind of shiny brushed metal pattern. Amazing!
