Fractal of the Day

|
Fractal visionaries and enthusiasts: I can't decide how to rate today's fractal -- this is why I named it "The Undecided One". I'm uncertain whether I like it or not. One glance pleases me, another displeases me. The striking reds and greens, which sometimes appear just right, at other times appear discordant and downright muddy. As a result of my indecision, I have not rated the image at all. I leave it to the viewer to rate the image as they see fit. To produce the image, the expression Z^(1.2)-0.9Z^(-1.3)+(1/C) was iterated by that most prolific of all my formulae, MandelbrotMix4. The parameter file renders in 5 minutes; the GIF image downloads in 1/5 the time. The image may be found at: The fractal weather here at Fractal Central today was cold and wet. The temperature topped out at 41F (+5C), which is too cold for the sensitive fractal cats, who got no closer to the outdoors than the window. I'll return tomorrow. Until then, take care.
