Fractal of the Day

Fractal visionaries and enthusiasts: For some reason I felt drained of energy all afternoon today. The lethargy was not enough to put a damper on the ongoing fractal search, but it does have me pretty well worn out and ready for a junky movie. Before the movie however we have a fractal to enjoy. The formula that drew the image is 0.075Z^(-10)+0.75(1/Z)+(1/C), which I found by entering numbers at random. The image is a rather sandy looking affair, which I named "Partly Curdled 'brot" for no obvious reason. Having put almost no effort into the picture, I rated it a below-average 4. The parameter file renders in 11-1/2 minutes. An easier way to view the scene is to give Paul and Scott a chance to post the image to their web sites at: Unfortunately, the FOTD will not be posted to Usenet until I straighten out the computer confusion, which should be accomplished in about one month. The fractal weather today was mostly sunny, with a temperature of 45F (7C), conditions that had the fractal cats romping in the fractal yard for over an hour. Well, I see it's shut-down time, so until next time, so-long for now. Jim Muth jamth@mindspring.com |
