Fractal of the Day
by Jim Muth

|
Fractal visionaries and enthusiasts: Today was an exceptionally busy one here at Fractal Central, leaving almost no time for fun with fractals. But I did find another midget. This midget is surrounded by what appears to be the petals of a sunflower, so that's the name I gave it. The expression -10Z^(-1.3)-Z^(-13)+(1/C) was calculated by the MandelbrotMix4 formula to create the image, which is not at all exceptional, rating a somewhat below average 4 on my scale of fractal worthiness. The parameter file's 9-1/2 minute render time is slow enough to make a download of the image file from: The fractal weather started deteriorating today, with lots of clouds and a temperature of 64F (18C). Recognizing less-than-perfect conditions, the fractal cats spent only a limited time outdoors. As for philosophy, there is none, but I'll return in 24 hours with a hopefully higher-rated fractal and more to tell about it. Until then, take care, and may the better man win.
