Fractal of the Day
by Jim Muth
|
Fractal visionaries and enthusiasts: Long ago, before the bridge across the Chesapeake Bay was built, there used to be a ferry that carried travelers to the eastern shore. That ferry was named "Smoky Joe". I never had the pleasure, or displeasure, of riding on that ferry, but my father rode it often, and frequently told of the thick black clouds of oily smoke that belched from the funnel whenever the ancient engines were running, sometimes choking the passengers and always marking the ferry's position even when the boat itself was below the horizon. For some strange reason, today's fractal reminds me of a ferry boat that I have seen only pictures of. The outer features surrounding the central midget do have a rather smoky effect, and the streaks of orange-red could be the reflection of a fire in a coal furnace, so I guess the name is justified. The formula Z^3+0.225(Z^5)+C is responsible for the smokiness, as well as everything else in the image, except for the coloring, which was created by the <tdis> inside fill option aided by myself. The rating of an above-average 7 is justified. The render time of a little over 8 minutes is slightly slow, but worth the wait. And as always, those who lack the computer time to render from the parameter file may see the image by visiting Paul's web site at: The fractal weather today was average, with a temperature of 81F 27C and big puffy white clouds that occasionally dropped a few large raindrops but never released their full potential. The fractal cats showed their approval by spending several hours in the yard, dodging the few raindrops. It's now 9am of the last day of July, and time to get a bit of work done. I'll return as always at the proper time. Until then, take care, and brace yourself for imminent philosophy. Jim Muth jamth@mindspring.com |
