    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.

zanella got me thinking more about math... d/6378 was basic color... this doesn't look like much but the theory is interesting to me....a circles-and-squares pseudo fractal, but with the added idea of "centers of gravity" from which the modular arithmetic create patterns against each other. it's incredibly slow so animation is almost pointless. but i like the idea still.
