FOTD -- February 11, 2012 (Rating 7) Fractal visionaries and enthusiasts: Today's FOTD image is named "Pentagram". It has nothing to do with werewolves or Satanic rituals however. The name refers to the near perfect pentagram star surrounding the central quintic minibrot. The parent fractal is a Mandelbrot set with Z^5 corruption so severe that it appears even on the surface, in the form of bits of debris in the interior of the buds, with a trace of this debris also in the main bay. Today's image lies in the debris cluttering the north part of the main period-2 bud of the parent M-set. The rating of an everyday 7 is all I could give the image. It's not all that impressive mathematically and it proved very difficult to color, but despite the rating the star around the minibrot is certainly worth a look. The calculation time of the parameter file is just over one minute, fast enough to keep impatience at bay and insure that little time will have been wasted if the image bombs. The hassle of setting up and running the parameter file may be avoided by visiting the official FOTD web site at: <http://www.crosscanpuzzles.com/Archives.html> and viewing the already calculated image there. The image is posted in high definition at: <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html> The classic FOTD web site with all the images since April 1997 may be accessed at: <http://www.Nahee.com/FOTD/> The weather took a definite turn for the worse here at Fractal Central today. Dawn broke with heavy clouds. Showers of snow began at midday and continued through the afternoon, growing even heavier at post time. The temperature hung around 34F +1C, so the pavements remained merely wet, but on the grassy areas the snow piled up to one inch, 2cm. The fractal cats enjoyed the big fluffy flakes for a while, then retired to the warmest places they could find. The humans, FL and I, took a short afternoon trip to a nearby antique emporium, making it back just before the temperature dropped. The next FOTD will be posted in 24 hours. Until then, take care, and I hear that married people tend to be happier than unmarried people. Does this mean that marriage brings happiness or that fewer want to marry unhappy people?
