Fractal of the Day

Fractal visionaries and enthusiasts: It's been another busy day here at Fractal Central, another day on which I lacked the time to do a proper fractal search and write a proper discussion. But I did manage to scrounge up a passable fractal. I named the image "Purplebrot" after the gloriously purple petals surrounding the central midget. The purple is made all the more vivid by the drab greens and tans along the outer fringes. Despite the haste in which it was found, the image rates an average 5. The parameter file renders in just under 16 minutes, which is a bit slow, but not as slow as waiting 11-1/2 hours for the GIF image file to be posted to Usenet at: In an hour or so, the image will be available on the Web at: The fractal weather here at Fractal Central today was sunny and mild. The temperature of 46F (8C) kept the cats comfortable on the porch. And that's it for this rushed day. It's well past the time to shut down the fractal shoppe and call it a night. Until tomorrow, take care, and see you in Fractal Land. Jim Muth jamth@mindspring.com |
