    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.

I thought the characters were underdeveloped but the effects hit the spot!
u/joeytwiddle

remixing jonbro and netgrind 's use of color in circle / square style patterns. added some hyperbolas. longer you stare at this the weirder the patterns get - it doesnt' repeat for quite a long time

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.
