FOTD -- April 21, 2013 (No Rating) Fractal visionaries and enthusiasts: On April 17 Mike Frazier posted an interesting image named "Black Gold". Today's FOTD is named "Black Gold Minibrot". The name indicates that I checked the center of Mike's image and not surprisingly found a minibrot. That minibrot appears at the center of today's FOTD image. I tweaked the colors to add a little variety, but made no changes to the parallel resistance formula itself. Since the image is a borrowed one I could give it no rating, but it's still a rather spectacular one to look at. The calculation time of one brief minute will cause no pain even for those with the busiest schedules. And the web sites are always ready to shorten even that brief minute. The finished image is posted at: <http://www.crosscanpuzzles.com/Archives.html> Variations are at: <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html> The FOTD back images are at: <http://www.Nahee.com/FOTD/> Nothing but sun fell on Fractal Central today, though the temperature of only 50F 10C was hardly spring-like. The fractal cat passed most of the day on his window shelf, watching for passing stray cats. When he finally saw one, his growl of defiance could be heard throughout the room. FL spent several hours working in her garden. As for myself, I simply spent the day. The next FOTD will be posted within a reasonable time. Until a reasonable time passes, take care, embrace the good and eschew the evil.
