FOTD -- January 12, 2009 (Rating 7.5) Fractal visionaries and enthusiasts: NEW FORMULA ALERT! Today's image is the first one created with a new formula, the DivideBrot6Julia, which draws the Julia aspects of the strange near-Mandelbrot set created by the DivideBrot6 formula. And speaking of near-Mandelbrot sets, today's image is the Julia set of a point in the East Valley of a small minibrot on the main spike of one of these strange things. And yes, I realize it looks nothing at all like a Julia set of the main spike of the Mandelbrot set, but what good would fractals be if they always did the expected. I have lost track of the shortest calculation time in FOTD history. The 8 seconds of today's image must be close to the record however. The name "Julia Starburst" accurately describes the image. The rating of a 7-1/2 seems about right for an image that took about a little less than no effort to create. If the calculation time of 8 seconds is still too slow, the finished image may be viewed at leisure on the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Cloudy skies and a temperature of 28F -2C on Sunday made clearing the 6 inches, 15cm, of snow from the Fractal Central pavements a task of sorts, but with the fractal cats offering encouragement from the windows, and two hot coffees courtesy of FL, I finished the job with minimum discomfort. The next FOTD will be posted in 24 hours. Until then, take care, and I can see no end in sight.
