FOTD -- March 11, 2010 (Rating 6) Fractal visionaries and enthusiasts: Well, I avoided another consecutive rating of 7, but I did it in the wrong way -- by creating an image with a rating of a 6. Yet a rating of a 6 is still a little above average, so why not settle down and enjoy the scene. With today's image we return for only one day to the workhorse MandAutoCritInZ formula. To create the parent fractal I sub- tracted Z^1.8 from Z^1.2 and added C. This parent fractal is a fairly normal Mandelbrot set rotated 180 degrees, so that its main spike darts out to the east, while its East Valley is on the west side of the main bay. So far, so good. But the East (west) Valley of the parent does not terminate in a point, it terminates in a broad wedge, with today's image being located on the southern edge of this wedge. The name "Amber Thumbs" now makes little sense, though I think it originally referred to the amberish elements surrounding the central minibrot. The rating of a 6 is at least honest, if not exceptional. The calculation time of 7 minutes borders on slowness. To avoid the risk of excess boredom, the finished image will soon be posted on the FOTD web sites at: <http://www.Nahee.com/FOTD/> and <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> I advise using the first address. The latter address will soon be dropped. The clouds moved in on Wednesday here at Fractal Central, but the temperature of 59F 15C kept things quite pleasant. The forecast is for a week of mild wet weather, so we'll see how things go from here on. The fractal cats, who never concern themselves with the future, were still dis-satisfied however. They missed the sun of the past few days. My day was fair and mild. I hope for a repeat tomorrow. The next FOTD will be posted in 24 hours. Until then, take care, and what is most real -- myself, Bugs Bunny or the Mandelbrot set?
