    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.

nice!
u/DirtyDan

Don't know what I was thinking having "+960+C(t)*i" in the first arc parameter -_- ... 11 extra characters!
u/DirtyDan

nvm, the +960 was necessary, not the "+C(t)*i"... 7 extra characters.
u/Purpzie

This is so beautiful.

Nice! Any particular reason you didn't initialize i to 6e3? That'd take care of that gap you have in one of the tendrils

Thumbs up for using the error output instead of the canvas. :)

nvm, 4 characters, dwitter should have edit comment feature t||(p=n=0);for(i=1e5;i--;)p+=(n++%2?4:-4)/(n*2-1);throw p
u/BuRRak

Oh no, just noticed it throws negative pi, just swap 4 with -4
