    if you can't beat the weird artifacts, say they're intentional :-)
  • u/joeytwiddle
    weird accidental artifacts are sometimes the best!

    13 chars over, this has been squeezed pretty hard, I don't think it's going to fit into 140.

    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

    Nice effect!

    this one was a huge pain to make fit even with the compression, I'll be really impressed if someone can golf it down to fit in 140 characters
  • u/vgel
    I finally was able to, by sacrificing some of the visuals: d/27314
  • u/tomxor
    Nice! I'm interested to dig into this in SDF form
  • u/magna
    Amazin!
