    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! Dwitter album covert art d/2108
u/jellyedwards

@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()))

This looks WAY cooler if you add x.filter='blur(4px)';

u/akm

woah, thats an awesome dweet and some crazy codegolfing!!
u/joeytwiddle

If I add that filter, flames start coming out of my laptop!

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.
u/Lazy1337

Not always true in creative coding/demoscene tbh
