Fractal of the Day
by Jim Muth

|
Fractal visionaries and enthusiasts: The day was another very busy one here at Fractal Central, as all days will be until I get settled into the new Fractal Central around the end of this month. But it was not too busy for me to find a fractal. To produce the parent fractal of today's image, I subtracted some Z^(-2.5) from some Z^(-2), added 1/C, and iterated 600 times. The outside was colored by the tdis method, which I find myself using more and more often when the classic method comes up blank. I named the picture "On the Diagonal" because that is where the midget is located. Considering the lack of effort I put into the picture, I could rate it only a 4, which is a bit below average. The parameter file renders in one very fast minute. And as always, the GIF file of the image is available on the Web at: The fractal weather today was cloudy, cold and rainy, with a temperature of 36F (2C) that confined the fractal cats to their window shelf. As I suspected yesterday, the forecasted monster snowstorm did not happen today, and the TV weather experts are once again doing damage control. That's it for today. But be patient, the rush will eventually end, and the FOTD discussion will return to its former glory. Until next time, take care, and be a happy fractalist. Jim Muth jamth@mindspring.com |
