FOTD -- September 09, 2003 (Rating 6) Fractal visionaries and enthusiasts: Long ago, there was a coal-burning ferry that plied the Chesapeake Bay, ferrying cars from Baltimore on the western shore to Love Point on the eastern shore. The boat was named 'Smokey Joe' because its whereabouts could always be determined by the plume of smoke that constantly rose from its smokestack. The ferry was in operation many years, but went out of service when the bridge across the bay opened. I came on the scene too late to ride the ferry, but my father often told of the times he had ridden it on his way to a special fishing spot, the location of which he never made clear. He described how the plume of smoke from its stack could be seen coming long before the boat itself became visible. I never saw the boat in operation, but in my imagination I often tried to picture the smoky ferry moving across the water, trailing its smoke behind it. For some reason, today's image reminds me of the plume of smoke that I never saw in person. The image is named "Smokey-Joe Midget" in honor of that never- seen but much-imagined ferry. The formula combines Z^(-8.8) with 8 times as much Z^(-0.88) and adds (1/C) instead of C. The resulting parent fractal is one of those indescribable things that result when two negative powers of Z are mixed -- a fractal with more valleys than a penguin has feathers. Today's scene is located at the point where one of these valleys splits into two separate valleys. The basic scene with outside=iter was acceptable enough, but I tried the other outside fills before deciding to evaporate the entire scene. None of the other outside options made an image that was worth the effort. Then I evaporated the scene by raising the escape radius to one-googol, and applied the various inside options to the blank screen that resulted. The 'bof61' option worked best, so that's the one I used. The end result rates a 6 -- not outstanding, but at least a little above average. The render time of 8-3/4 minutes is acceptable, but the image may be seen far more quickly by downloading it, already rendered, from Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Monday ended in a satisfactory manner here at Fractal Central, with contented cats and up-to-date work. True, the clouds thickened as the afternoon progressed, but no rain fell, and the temperature of 79F 26C kept things comfortable for the cats. Today is starting the same as yesterday. I hope for another good day. Until 24 hours from now, when the next FOTD appears, take care, and don't get spammed.
