Uh, wow, I think they earned that claim. There's so much in here, they even have a cow which fires lasers being dropped from a space shuttle. http://www.oftenpaper.net/img/understandingtheriemannsphere....

seriously going to have to look more closely at this some time, it's fascinating in a "look what you can do with math/programming/mathematica" kind of way.

Holy mother, this person is cool and this person's website is cool, too: http://www.oftenpaper.net/ (it even has an article on Arc coroutines, ha!)

I especially like the way they present images + source as annotations in their article.

For those who happen to have Mathematica, try this to get a smooth, high-resolution interactive fractal explorer (make sure you have a C compiler installed):

  JuliaFP = Compile[
    {{const,_Complex}, {init,_Complex}}, 
    Module[{val=init,n=0},
      While[Abs[val]  "C", 
    RuntimeAttributes -> Listable, 
    RuntimeOptions -> "Speed"
  ];
  
  {fine, coarse} = Table[Complex[j,i], 
    {dx, {0.008, 0.002}}, {i,-1.5,1.5,dx}, {j,-1.5,1.5,dx}
  ];

  pt = {0.0,0.0};
  Graphics[{
    Raster[
      JuliaFP[Complex @@ pt/2, If[ControlActive[], fine, coarse]], 
      {{-2.0,-2.0}, {2.0,2.0}}, 
      ColorFunction-> Hue
    ],
    Locator[Dynamic[pt]]},
    ImageSize -> 800
  ] // Dynamic
P.S. Original post is awesome. I love the cow!

http://draves.org/pix/frame3.cgi?zoom=1&dir=flames&file=205.... one he missed, from the early 90s

He did not. Fractal Flam3's are the chaos game.

to quote:

  1 start at any point. call it p
  2 pick one of the three vertices at random
  3 find the point halfway between p and that vertex
  4 call that point p and draw it
  5 goto 2
He goes into great depth about this strategy.
