FOTD -- June 07, 2013 (A-7,M-6) Fractal visionaries and enthusiasts: Today's intricate fractal came to life when I rendered a relatively ordinary fractal with the 'outside' set to 'fmod' and the proximity set at 0.25. This 'fmod' option all too often results in little more than a flat blank screen, but when it does work, as it does in today's image, the results can be well worth the effort. Today's generating expression combines Z^(2.05) with straight Z before adding straight C on each iteration. The resulting parent fractal resembles two partially merged Mandelbrot sets. Today's scene lies in the outer debris on the west shoreline of the main bay. The name "Bright Shadows" has nothing to do with an old TV soap opera. It refers to the brilliant patches spotted throughout the frame. With a rating of a 7, the image's artistic worth exceeds its math worth, which scores a rating of only a 6. The calculation time of 1-1/3 minutes will worry no one, especially those who choose to view the image on one of the web sites. The finished image is posted online at: <http://www.crosscanpuzzles.com/Archives.html> with an enhanced rendering at: <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html> Thousands of past images may be checked and admired at: <http://www.Nahee.com/FOTD/> Today began cloudy here at Fractal Central and went downhill when the rain from T.S. Andrea arrived at noon. The chilly temperature of 66F 19C failed to bring cheer. The fractal cat gave up early and spent most of the day in my favorite chair; the fractal humans, who never give up, strongly disapproved of the weather conditions. I doubt that there will be time to produce a FOTD fractal tomorrow, so the next FOTD will be posted in two days. Until then, take care, and avoid becoming attached to any particular fractal. They have a way of vanishing without warning into the ether. (BTW, what is this 'ether' that things vanish into?)
