Fractal of the Day

Fractal visionaries and enthusiasts: Unfortunately, with a viral attack, I am not feeling up to par, (me, not the computer), so today's discussion will be brief. The left half of today's image is half evaporated; the other half is normal. And the dividing line runs right through the center. I'll not describe the parameter tricks that created the unusual effect. They are clear from the parameter readings. The rating of a 7 seems appropriate for such an unusual image. The name "Two Sides of a Coin" describes the two dis-similar halves of the picture. The calculation time of 10-1/4 seconds is so fast as to be completed almost before it starts. And if running parameter files is inconvenient, the finished image is posted for instant enjoyment on the FOTD web site at: The temperature reached 41F 5C here at Fractal Central on Sunday, but heavy clouds kept the mood depressed. At least, the forecasted rain held off until after dark. The fractal cats held off asking for their daily treats until after dark also. Ignoring the coughs and sneezes, my day was fair enough. The next FOTD will be posted in 24 hours. Until then, take care, and search through the darkness for the light. Jim Muth jamth@mindspring.com jimmuth@aol.com |
