FOTD -- March 01, 2003 (Rating 5) Fractal visionaries and enthusiasts: This will be the last daily FOTD until the Fractal Central chores have been finished and the FOTD-CD is ready. I simply do not have the time to do the work than needs to be done and bring the CD to a fully-functional condition while keeping the FOTD going on a daily basis. Until the other work is finished, the new FOTD's will appear on a weekly basis on Saturday evenings Eastern Standard Time, which is five hours behind Greenwich Time. On the other six days, I will be spending my limited spare time catching up on repairs and doing what I should have done at the start to make the FOTD disk fun to use rather than a puzzle. (As a curious side note, the kind of oversights I made in the preparation of the disk are the same kind that I sometimes criticise my custo- mers for making in the jobs they bring.) Today's image combines portions of Z^2, Z^3, Z^4, and Z^5, a combination that has its critical point at zero, making tedious calculation unnecessary. The parent fractal is a rather normal Mandelbrot set surrounded by disconnected satellites. Today's scene is located in a minor valley on a spurious caterpillar- like feature that appears on the negative X-axis, some distance beyond the tip of the main negative stem. I have named the image "Ring of Fire" not because of any volcanic appearance, but because of the brilliant red-and-yellow ring of fractal elements surrounding the midget. The rating of 5 means I consider the image to be merely average. But it is still an interesting scene, perhaps not quite worth the 24 minutes required to render from the parameter file, but still worth the small effort of downloading it from one of the FOTD web sites at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The weather Friday stayed cloudy all day. In the afternoon the temperature rose to 38F 3C, but this just made the snow wet and sloppy -- far too unpleasant for the cats' paws. They passed the day sleeping by the heat and occasionally asking for food. 12-year-old cats are not known for unnecessary activity. As for me, I'm taking a break in the FOTD until the above- mentioned chores are finished and the much-advertised FOTD-CD is ready for distribution. Until next Saturday, take care and have no concern. I am not losing enthusiasm. I will continue to be active on the lists, and the FOTD will resume its daily basis as soon as the other tasks are finished.
