Fractal of the Day
by Jim Muth

|
Fractal visionaries and enthusiasts: It was another busy day as I fought with a stubborn computer, but as always I did manage to find a quick fractal. I named the image "Cobwebs" because that's what came to mind as I studied the scene. I rated it a below-average 4, mostly because I've seen and rejected too many similar images in my fractal travels. The formula 0.2Z^(4)-0.2Z^(-6)+(1/C) is responsible for the image. The render time from the parameter file is a fast 2 minutes. Since I still have not regained access to Mindspring, the image file will not be posted to Usenet, though it will be posted to Paul Lee's Web site at the URL: The fractal weather today was sunny but very cold, with a morning temperature of 14F (-10C) and an afternoon high of 26F (-3C). Such temperatures keep all fractal cats including Thomas and Tippy snug indoors. I'd write more, but I'm exhausted after fighting most of the day with a crashed computer. Hopefully, tomorrow will bring a better mood and a better fractal. Until then, take care, and we'll never run out of fractals. Jim Muth jamth@mindspring.com |
