Fractal of the Day

Fractal visionaries and enthusiasts: Another evening with telephone problems, and a C-FOTD to post. I wonder if I'll ever get it sent on its way. I'll cut the notes short just to be safe. It would be a shame if the picture doesn't make it, but that's the way it goes sometimes. The formula behind the image is -2(1/Z)-Z^(-2)+(1/C). Yes, I realize that it's whimsical -- almost all my fractals are. That's what makes finding fractals with M-Mix4 such fun. I named the picture, which rates a 7, "Silversmith". I have no idea why. I guess it has a bit of silver color in it. With a render time of 7-1/2 minutes on a 200mhz Pentium, the parameter file is a bit slow. The better choice is to download the GIF image file from the Usenet binary newsgroup: The fractal weather today started rainy but cleared in the afternoon. The temperature of 46F (8C) was mild enough, but due to the wetness, the fractal cats remained indoors. That's it for today. I'll return tomorrow with another interesting fractal. And one of these days I'm actually going to deliver some philosophy. Until next time, take care, and the longer it takes the philosophy to appear, the more profound it will be when it does.
