    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.

liked this method alot. remix https://www.dwitter.net/d/2037
u/hypothete

your noise generation here is slick, is this a technique of sorts or just trial and error?
u/recursive

Both. I wanted to be random, but I didn't want pure static. I wanted nearby pixels to have similar levels.
