Fractal of the Day
by Jim Muth

|
Fractal visionaries and enthusiasts: To see today's image properly it must be viewed in a subdued light that lets its brilliant spots glitter like stars in the desert sky. The midget at the center, as bright as a midget can possibly be, serves as the focus of attention for the whole scene. Since the image reminds me of the desert sky as seen on a moonless night from a spot such as a ridge in northern New Mexico, I named it "Star-Bright". The formula Z^1.8+C created the parent of today's image, which is a totally confused Mandeloid easier observed than described. Today's scene lies in a broken spiral in a blunt valley in a mis-shapen bud on the northwest shore of the main bay of its parent. I rated the image a 6. It might have been worth a 7 were it not for the fact that most of its impact is lost when it is viewed in normal light. The inconvenience of dousing the lights is compensated for by the short render time of 2 minutes of the parameter file. And as always, the download of the GIF image will be available in a few minutes from the following web sites: The fractal weather Tuesday here at Fractal Central started good enough, but before noon a heavy cloud deck moved in, which held the temperature to 55F 13C and spoiled the cats' planned lounge on the porch in the warm afternoon sun. I told them that in the seasons when the sun is low they have only the hour or so of sun that manages to sneak between the holly trees each afternoon, but they got cranky anyway and sulked until I gave them a treat of tuna around sunset. And right now I'm going to treat myself to a day's work. Until next time, take care, and look to the stars for inspiration. Jim Muth jamth@mindspring.com |
