Fractal of the Day

Fractal visionaries and enthusiasts: The hot streak continues unabated. Not only is my fractal philosophy once again active, but my fractal images are active also. And all this action piled up on a day with so many mundane chores needing to be done. With today's image we're back up to a superior rating of 8. If the present trend continues, we may reach one of the very rare 9's, or possibly even an unheard-of 10 before long. To create today's fractal I entered the parameters for -2Z^(-1.1)-0.0002Z^(-11)+(1/C) into the MandelbrotMix4 formula, and let her rip. Today's scene lies at the end of a curving filament extending from a bud, very near the point where many filaments converge into a starlike object. I named the image "Cometary Impression" when I saw the eight elements around the midgets and imagined eight circling comets. The parameter file render time of 13 minutes is slow. The download is fast, and will be available shortly on the Web at: The fractal weather today was variably cloudy and breezy. The wind and temperature of 75F (24C) kept the fractal cats indoors most of the day, frequently checking the door to see whether it was still breezy outside. Later in the afternoon the wind died down and the cats went out, scolding me for not turning down the wind earlier. The time is now after 1am -- most certainly time to shut down the fractal shoppe and throw the big switch. Until next time, take care, and have faith in your fractals. Jim Muth jamth@mindspring.com |
