FOTD -- April 25, 2013 (Rating 7) Fractal visionaries and enthusiasts: Today's image is named "Butterfly Cookies". The obvious reason is that it reminds me of butterfly cookies. In fact, it reminds me so much of the cookies that, when I saw the image, I ran to the local store to pick up a box. The recipe behind the cookies combines a measly 0.1 part of Z^2 with a full part of Z^(-3) then adds C on each iteration. The resulting parent fractal is an oversized thing closely resem- bling some of those created by the parallel-resistance formula posted on the list a week or so ago. Its Mandelbrot shape is apparent, but the normally empty inside parts are filled with all kinds of superfluous decorations. Today's scene lies on the X-axis just beyond a large minibrot on the skeletal negative spike. The rating of a 7 is an improvement over yesterday's, but still leaves lots of room for improvement. Hopefully, tomorrow's image will rate an 8, but there is no guarantee that it will not check in at a rating of an embarrassing 6. One thing not in dispute is the speed of today's image. On my far from SOTA machine it finishes in 20 seconds. Some of the current units will finish it in far less time, that is if they can run the old Fractint DOS program at all. Regardless, the image is available on the FOTD web sites. The official FOTD web site with the finished image may be found at: <http://www.crosscanpuzzles.com/Archives.html> Augmented variations of the image are online at: <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html> and the FOTD back images are at: <http://www.Nahee.com/FOTD/> The weather was near perfect here at Fractal Central today, with photoshop (old-kodachrome) blue skies and white cotton-puff cumu- lus clouds. The only thing not perfect was the temperature, which at a high of 57F 14C was notably chilly for late April. The fractal cat would have preferred more sun on his shelf. But now that the sun is at a much higher angle it strikes only the edge of the shelf closest to the window. The humans, not very concerned with sun angles, had an average day. The next FOTD will be posted in a number of hours. Until that mysterious number of hours passes, take care, and thanks to science we have life better today than at any time in the past. Why then are so many people dis-satisfied with their lives?
