got inspired by d/16174 for some ways to shrink it further :-)
u/Xen

shaved a few: for(w=p=c.width|=H=Math.hypot;p+=279,X=(Q=p%w)/1e3-1,p<2e6;x.fillRect(Q,W,s=60/i,s))for(Z=i=D=1;++i<9&D>.1;)Z-=D=H((H((C(t)*X-S(t)*Z),(W=p/w)/500-1)-.4),(C(t)*Z+S(t)*X))-.1

Black hole

u/katkip

this is very heavy but stylish! awesome!
u/rep_movsd

It slows to 5 FPS on my system - it draws 23000 rectangles per frame - runs well on my test webpage - I guess the scaling causes issues
u/sigveseb

Pretty!

Shave 3 chars: (i>>5)*C -> i&-31
u/KilledByAPixel

you can also do i>>5*C, but both ways distort the image
u/aleamb

u/Jasper

I don't rightly know why, but i&-32 seems to work without distortion as far as I can tell
u/KilledByAPixel

Oh wow, nice!
