Fractal of the Day

Fractal visionaries and enthusiasts: On some days I just can't find a fractal. Those days give me the minibrot blues, which just happens to be the name I attached to today's C-FOTD. The image, with its somber blues and purples, effectively captures the mood I feel when unable to find my Classic Fractal of the Day. After studying the picture for all of 2 minutes, I rated it a 6, which is 2 points higher than yesterday's spooky C-FOTD. Actually, I would have rated yesterday's image 3 or 4 points higher, had I not already done so many of this type of image over the years. The fractal formula 2Z^(-1.2)+0.4Z^(-12)+(1/C) was iterated by M-Mix4 to create today's image. The render time of the attached parameter file is around 8 minutes on a 200mhz Pentium machine, making it quicker to download the GIF image from: For all who are interested, the weather today at Fractal Central was partly sunny and 56F (13C) -- conditions the fractal cats approved of. They showed their approval by passing the afternoon lounging in the off-and-on sun. When the sun went behind the hemlock tree, they came indoors for their meal. That's it for now. I'll be back in 24 or so hours with more fractal surprises. Until then, take care, and be surprised. Jim Muth jamth@mindspring.com |
