Fractal of the Day

Fractal visionaries and enthusiasts: I've had another very busy day, and it's now 1:50am, so this will have to be brief. Today's fractal is another one that was found with the aid of the MandelbrotMix4 formula. It's a rather somber image, with rings of sparkling highlights. I named it "Spindles" when I noticed the spindly arms radiating from the little Midget at the center. Actually, the spindly arms are far more prominent beyond the borders of today's image, but when calculated at that lesser magnitude, much of the inner detail is lost. The rating of 6 might have been a 7 if I had had more time to work with the color. With a render time of 13 minutes, the parameter file tries one's patience. By far the best way to view the picture is to download the GIF file of the image from Usenet at: The fractal weather was perfect today. But the cloudless sky and temperature of 72F (22C) made the fractal cats a bit too active when let outdoors. At one time, normally placid Tippy dashed across the street and was retrieved only after a brief chase. The philosophy is brewing; the topic is still not determined. I'll return with further fractal activity in 22 hours. Until then, take care, and I wonder when they'll start giving gold medals for fractal excellence. Jim Muth jamth@mindspring.com |
