    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.

Excellent! 1/Y/2 as alpha channel gives a softer water surface imho. :-)

Even better: x.fillStyle=R(i/2,h*4,h*p,1/Y/6)
u/taupelink

thanks all--and yes, I like that variant!
u/magna

u/taupelink how much of your work is intention versus happy accidents? It would be lovely to see a blog post from you explaining your process...
u/taupelink

far, far closer to happy accidents. lots and lots of trial and error to see what works. with that said, it's not just throwing darts blindly. maybe like panning for gold?
u/taupelink

in any case, i will think about writing up some kind of essay on it!
