    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.

Maybe someone can add a black background, but I'm not good enough at golfing down js code to this. #matrix

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