Fractal of the Day

Fractal visionaries and enthusiasts: Today's image resembles a . . . well, I just don't know. I named it "Iterative Blues" on a whim, and rated it at a 7 because it's a bit on the unusual side. The image is a brief excursion into the fractal world that is created when portions of Z^(-1.4) and Z^(-7.4) are combined, and (1/C) is added. Like so many interesting fractal images, today's image is found deep in a valley of its parent. (The parent has countless valleys.) Apparently, the valley has some of an East Valley nature to it. Many of the characteristics associated with East Valleys are present in the image. The render time of 9 minutes is true on my 10-year-old P200 machine, which is basically useless on today's internet, but which loads DOS 6.22 and, as long as it continues to run at all, (which might not be too long), will run Fractint perfectly. I am a bit puzzled (and rather amused) by the ongoing fuss about S.O.T.A. Windows-XP computers and video cards that have not been told how to run DOS programs. If your present machine is over-qualified, go out and pick up an older unit that is inadequate for the internet, and dedicate it to Fractint. They are practically being given away. BTW, is Fractint the last DOS program still being actively used? (Maybe not. I write my FOTD discussions using WordPerfect 5.1) As I said earlier, today's image renders in 9 minutes. That time may be saved by going to the FOTD web site at: With a high temperature of 91F 33F, things were a bit sultry here at New Fractal Central on Monday. The new fractal cats must have agreed. Except for Nicholas scratching around his ears, they kept their activity to a minimum. And I must keep an eye on the scratching. Nicholas could have picked up fleas. The evening treat of tuna went peacefully, with no one trying to steal the other's food. For me the day was un-notable. The next FOTD will appear in 24 hours. Until then, take care, and everything that exists is a paradox. Jim Muth jamth@mindspring.com jimmuth@aol.com |
