    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.

Many of the start points exhibit patterns, e.g. t=98.99+t/2e2
u/vain

WTF? Amazing!
u/joeytwiddle

This was a happy accident. I was drawing a spiral, and thought "What if the arms rotate with i*i instead of i?" Of course, this makes the outer points spin faster, and distributes the points semi-randomly.
