    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.

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

golfed down by 2 characters t||(p=0,n=1);for(i=1e5;i--;)p+=(n%2?4:-4)/(n++*2-1);throw p
u/BuRRak

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

@joeytwiddle yours looks much more like it! I had a few other versions with fBm and fill etc. but couldn't get them under 140 chars!

If someone can shave 2 characters off, we can invert the colors! Like in d/7011

u/akm

here, I shaved off 10 chars: with(x)for(fillStyle="#FFF",i=0;i++<44;lineWidth=44)beginPath(arc(960+S(a=t*i/11)*(d=i*t*S(t)),540+C(a)*d,i*3,0,7),fill(stroke()))

Mostly an accident, but it looks cool anyway

u/DirtyDan

Pretty sure most dweets are, lol
u/artfarnaa

Every artist from every domain says same thing. Nothing great emerges without the author saying it was just an accident.

Not always true in creative coding/demoscene tbh

I used a different strategy for the transform and managed to salvage enough characters to animate it.
