FOTD -- November 26, 2010 (Rating 7) Fractal visionaries and enthusiasts: Things were rather busy here at FC on Thursday, which was the holiday on which we give thanks for something I'm not quite sure of. But despite the activity I found time to locate a worthy fractal. I took the parent fractal of three days ago and cut the portions in half. The effect was to do little more than double the size of the parent. Instead of lying in a valley at the southern edge of the 'fan' of the parent, today's scene lies in a spiralling filament extending from a twisted minibrot on the southeastern edge of the fan. The name "Spiral for the Ages" is admittedly overblown. The chief feature in the image is the minibrot, not a spiral. The rating of a 7 is about what the scene is worth. If I had more time, I might have improved the colors and raised the rating a half point or so. The image calculates in just one minute -- in the super-fast category. No time will have been wasted if disappointment prevails after the minute. And the image is always available on the FOTD web site at: <http://www.Nahee.com/FOTD/> Thursday began with snow and sleet here at Fractal Central. For a while it looked like a white Thanksgiving was in store, but by late morning it all changed to rain and within an hour the centi- meter or so of snow that had piled up was gone. The fractal cats kept careful watch on the big floppy flakes for an hour or so, then decided to ask for food. The temperature rose during the day from 32F 0C at daybreak to 39F +4C at nightfall. My day was pleasant enough. FL kept the two guests who were expected well supplied with food, while the foul weather kept any unexpected visitors from dropping by. The next FOTD will be posted in 24 hours. Until then, take care, and what will the next media-manufactured crisis be? It's already got me worried.
