    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.

Shortened by a whopping 55 characters

inspired by @Purpzie #interference i simplified an old one ... what fascinates me is the entire pattern is based on modulo function applied to Quadrance, there is no cosine, sine, trig, or even really commands to draw colors based on posiiton. #waitforit

sorry meant to post that on my remix
