    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.

.618 is an approximation to the golden ratio. Putting .5 == 1/2 will create 2 spokes. Similarly .6 == 3/5 will create 5 spokes.

Cool!

Going to take a three month sabbatical and figure out how this works.
u/FireFly

Anything in particular that I should explain? It might help to draw the bits of the codepoints in the string literal on a piece of paper, as an 8×15 grid (15 chars, 8 bits per char). Ā is U+100, used to encode 0x00.
