What says fractal more than a spiral of self-similar spiral? Well if I get pedantic "fractal" says "fractal" more than anything
else but I'm talking rhetorically here. This post has two graphics, a Fractint compatible gif and an anti-aliased jpg.
I used my usual technique to anti-alias. The original 800x600 gif was regenerated to 3200x2400
resized to 800x600 in Gimp 2.6.8 sharpened a bit and saved as a 800x600 low compression jpg.
To compare the two you'll have to go to http://maxitersfractalfollies.blogspot.com.
