FOTD -- February 15, 2005 (Rating 9) Fractal visionaries and enthusiasts: To add a bit of variety to today's adventure, I changed the portions of Z in the parent fractal that I have been exploring for a week. Instead of positive portions, we now have negative portions. This change creates an even more interesting fractal. Yesterday's image turned out so well that I tried the same partial-evaporation trick again today. I rendered the scene with the inside set to 'bof61' and the outside set to 'tdis'. The resulting image rates another 9. I found today's scene in a part of the parent fractal shaped like a fan. There are many more unusual features in this new parent fractal, which I will be exploring for a few more days before moving on to something entirely new. Much of the purpose of fractals is simply amusement. This is the reason I named today's image "Iterative Amusement". The relatively fast render time of 3-1/2 minutes makes the image that much more amusing. The image may be seen in even less time by downloading it from the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> It rained all day Monday here at Fractal Central, keeping the fractal cats safely confined to their indoor shelf by the win- dow. They had one thrilling moment when a squirrel carelessly climbed onto the ledge outside the glass, and they both sprang to the attack. When the squirrel saw two cats eyeing him, he took off like a bat out of you-know-where. Today is starting cloudy, but it is milder, and promises to be far more pleasant, both for the squirrel and the dynamic duo. For me, it will be a satisfactory day if I end it with no work piled up. The philosophy is still a couple days off, but the next FOTD will appear in 24 hours. Until then, take care, and think kindly of your amusing fractals.
