Fractal of the Day
by Jim Muth

|
Fractal visionaries and enthusiasts: Today's image has no midget at the center. In fact, I doubt that it has any midgets at all hidden in its depths. But it is still a striking enough picture to rate the honor of being declared a FOTD. I gave the picture neither name nor rating. If I had named it, the name would probably be connected to leaves or butterflies. A rating would have been something like a 6 or 7. A curious feature of the image is its near, but not perfect, symmetry around the Y-axis. For parameters I used the same four irrational numbers. I switched the signs of 1.4142 and 1.618 to add a bit of interest. The render time of 3-1/2 minutes is fast enough so that a download of the completed image from: Increased clouds made little difference here at Old Fractal Central on Wednesday. The temperature remained warm and the fractal cats enjoyed a comfortable afternoon in the yard. My day was quite busy. Despite the stuff that still needs to be done, I expect another FOTD to appear in 24 hours. Until then, take care, and work for the right. Jim Muth jamth@mindspring.com jimmuth@aol.com |
