Fractal of the Day

Fractal visionaries and enthusiasts: Today's rather slow image rates only a lowly 3. If I worked on the colors, I could raise it to a 5 or 6, but due to the world news, I just don't have the enthusiasm necessary to work with fractals. I named today's image "A Vision of Sylphs". A sylph is an elemental nature spirit that dwells (or is supposed to dwell) in the air. Having never seen a sylph, I have no idea of their appearance, but some of the elements in today's image give the impression of a swirling dance of atmosphere. This is reason enough to justify the name. The formula of the image is Z^1.55+C, sliced 97 levels up the logarithmic spiral. The render time of 43 minutes is far too long for such a disappointing image. A far better way to see the sylphs is to download the GIF image from the W.W.Web at: The fractal weather Sunday here at Fractal Central turned cloudy and chilly. No rain fell, but the temperature of 52F 11C and lack of warm sun limited the fractal cats' time outdoors to less than an hour. When they can't go out, the cats get hungry, so they spent most of the afternoon indoors, worrying me for more food. Right now I'm worried about some work that should be finished but is not. The best way to finish it is to start. And though I don't feel like doing so, that's what I'm about to do. Until next time, take care, and what is wrong with humanity?.
