Fractal of the Day

Fractal visionaries and enthusiasts: Another very busy day has come and gone here at Fractal Central, a day that produced a most colorful fractal. Yes, today's FOTD image is one of my most colorful, though strangely enough, the colors give little impression of gaudiness. The image was created by the iterated formula 2Z^(-2.2)+2Z^(-1.1)+(1/C). After some thought, I named the image "A Riot of Color". I decided on the name after studying the image and finding myself unable to ignore the unusually brilliant colors. I rated it a 6, mainly because of the colors. I am now using patch 9 of the float-only version of Fractint, which as far as I can tell is free of major bugs. However I have seen reports of video problems with this version, which luckily do not show up on my dedicated fractal machine shackled as it is by a humble video card with a mere 1 meg of memory. I use the float-only version because its smaller footprint permits me to shell to DOS even with all the TSR's loaded, and for some reason, it also runs marginally faster. (DOS is an old abandoned operating system, which nobody in their right mind would still be using.)  Luckily, I'm not in my right mind.  Since today's parameter file is a rather slow one, a download of the GIF image is strongly recommended. That file will soon be posted to Paul Lee's web site at the URL: The fractal weather today was brilliant, with deep blue cloudless skies, a gentle east wind and a temperature of 65F (18C). The cats approved of these conditions by sleeping all afternoon on their porch chairs. And now it's almost midnight -- time to shut down the fractal shoppe and settle into my ponder chair to fall asleep watching a junky sci-fi film. I'll pull a video tape off the shelf at random . . . I just picked "Deadly Ray from Mars"! That should be junky enough. Until tomorrow and another fractal, take care, and there's a 50 percent chance that the world is at least as real as a fractal.
