Fractal of the Day

Fractal visionaries and enthusiasts: Yes, yes, I realize that the FOTD is once again late. It's late because I spent most of my spare time today organizing the new Fractal Central auxiliary HQ, leaving me little time for fun with fractals. But by entering values at random and searching aimlessly, I managed to find a fractal worthy of being declared today's FOTD. I named the fractal image "A Midget Eruption". The reason is most likely that I was impressed by the eruption of unusual features in the elements surrounding the ever-present midget at the center. The overall pattern resembles the typical Julia pattern that characterizes midgets found in the East Valley area of larger midgets, but today's midget has far more intricate detail than most. I have rated the picture a 6, the fourth or fifth 6 rating in a row. It's really quite an interesting scene. Maybe if I had more time to appreciate it, I would have rated it higher. The parameter file renders in under 9 minutes, slow enough to make a download of the GIF image worth the effort. That image will be available in an hour or so at: The fractal weather today was unpleasant -- cloudy and chilly, with just enough light rain to keep the fractal cats confined to the indoors. Afternoon temperatures in the 50's F (lower teens Celsius) did not help. And now it's late, or more accurately, early, and I've got a lot of organizing to do. So until the next FOTD, take care, and all rushes eventually come to an end. Jim Muth jamth@mindspring.com |
