Nice concept, I'd like to see it paralax!

@Xen - can you post the above as a remix? it seems to have errors - is it a parallax version?
u/Xen

not parallax just mildly golfed sorry

Black hole

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

Pretty!
