Fractal of the Day

FOTD -- January 14, 2009 (Rating 7) Fractal visionaries and enthusiasts: An unexpected last-minute change on a job we thought was already finished left little time for fractal diversion on Tuesday. But the MandAutoCritInZ formula makes interesting fractals almost automatically, and using it, I found an emergency image in a few minutes. The parent fractal is one of those double minus things with a prominent fan extending east from the origin. Today's image is located in a small valley at the edge of the fan. I named the image "Less Than Nothing", which probably refers to the effort I put into it. The rating of a 7 seems fair. The calculation time of 9 minutes may be avoided by surfing to the FOTD web site at:and viewing the finished image there. Cloudy skies, a temperature of freezing and occasional periods of snow kept the fractal cats in poor spirits here at Fractal Central on Tuesday. The changes to a supposedly finished job kept me in poor spirits. The next FOTD will be posted in 24 hours. Until then, take care, and choose wisely. Jim Muth jamth@mindspring.com jimmuth@aol.com |
