Fractal of the Day

Fractal visionaries and enthusiasts: I'm depressed today. Maybe it's because yesterday I lost the article that I spent several hours writing; maybe it's because of the discouraging events on the Fractal-Art list. Whatever the reason, I seem to have no energy to write -- but I'll still get in a few words. Today's unimpressive picture is another view of the quintic midget that appeared in the n-e-s-w picture of October 28. This time we see the midget from the Rectangular direction, which shows the midget as a roughly rectangular hole with a pair of tiny bridges across it. The pattern around the midget and the color palette are almost exactly the same as the image of 2 days ago. I named the picture "Quintic Rectangle" as a description. I rated it a lowly 4 because I don't think that much of it. The parameter file renders in under 5 minutes, which is slow enough to make the download the better choice. The GIF image has been posted to Usenet at: The fractal weather today was sunny but the 57F (14C) was too chilly for the cats' outdoor adventure. They spent the day chasing spots of sunlight around the house instead. And I'm going to spend the rest of the evening dozing in front of the TV, with a junky horror movie playing. But barring the unexpected, I'll be here again tomorrow, with another fractal. Until then, take care, and when the blues come calling, chase them with a fractal. Jim Muth jamth@mindspring.com |
