    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.

jylikangas treatment ;)

u/jylikangas

I was so happy to come up with that trick but even happier now to see it repeated. I found it when I wanted to emulate the appearance of a Vectrex console.

I was inspired by https://twitter.com/beesandbombs/status/1221… I wanted to see if I could draw it with one stroke. Then I just started playing around. +C(r)/2 does most of the work here, if you delete it you can see the reference shape.
u/pavel

%24 is only there to avoid a bug in Safari from angle being too big on arc. /3.8197 is short for *Math.PI/12
