Fractal of the Day

Fractal visionaries and enthusiasts: Recently, I have had occasional trouble getting connected to Mindspring, which is why some recent FOTD's have been posted through my AOL account. Unfortunately, the Philofractal list does not accept postings in the AOL format, which is why the philofractal posting might be later than usual. Hopefully, I can solve the access problem by switching to another Mindspring (Earthlink) access number. We'll see how it goes. Today's fractal goes very well indeed. One glance at the image shows why I named it "Blue Sea Shells". It could easily be a glimpse of a fantastic under-water garden. To reward myself for the small amount of extra effort I put into the coloring, I added an extra half point to the rating of a 7. The parent fractal sprawls far beyond the edges of the default opening screen, but the central feature is a string of bays which together resemble a large ant with a long mandible. Today's scene is located about halfway to the tip of this mandible. The calculation time of just over 2 minutes should be no problem. But if the unexpected happens and calculation becomes problematic, the image may also be seen by going to the FOTD web site at: After a foggy start, Tuesday turned out to be a great day here at Fractal Central. The temperature of 63F 17C, clear skies and light winds pleased the fractal cats, who finally took notice of the pigeons taking up residence under the eaves of the house next door. With two such alert cats on patrol, those birds had better start pecking for food on some other sidewalk. My day was notably calm, and if all goes as planned, tomorrow will be the same. The next FOTD will be posted 24 hours from now. Until then, take care, and things may not be as they seem. Jim Muth jamth@mindspring.com jimmuth@aol.com |
