    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.

https://link.springer.com/article/10.1007/s0… Golden *morphic* angle for circles. 76.34541 if you want degrees. Both are the best *and* shortest single float approximation respectively. The traditional golden angle of 137.50777 degree (2.3999631 radian) has its uses, but this one has a few more tricks up its sleeve.
