FOTD -- December 11, 2010 (Rating 7) Fractal visionaries and enthusiasts: Today's image takes us back to the MandAutoCritInZ formula, still the most productive formula in my oversized and underused collection. I named the scene "The Midas Untouch" because sometimes every fractal I find seems to turn to lead. Most of the effect of today's image is due to its coloring. The sinuous bands that hold the golden colors were created by rendering the scene with the outside set to 'tdis'. The rather unlikely generating formula combines 8.4 parts of Z^(-2.2) with 17.5 parts of Z^(-5.2) then adds (1/C). The par- ent fractal is a shapeless thing with a large but disconnected minibrot just southwest of the main body of the fractal, which is one of the most twisted minibrots I have yet come upon. Today's scene lies in the East Valley area of this minibrot. The rating of a 7 makes the 47-second calculation time a bargain. Other bargains may be found at the following web sites: <http://www.fractal-animation.net/fotd2.zip> <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html> <http://www.Nahee.com/FOTD/> where the finished image soon will be posted. Clouds moved in just after sunrise and hung tough here at Fractal Central the rest of the day on Friday, tough enough for about 1/2 inch, 1cm of snow to fall in the afternoon. The temperature rose from 16F -9C at sunrise to 30F -1C in the afternoon, assuring that the small snowfall made things slippery. The fractal cats grew bored watching snowflakes after a half hour, and spent the rest of the afternoon in a warmer location. My day was quite busy trying to clear away a lot of little nuisance jobs. The next FOTD is due in 24 hours, but with the holiday rush near its peak I will give no guarantee that it will be ready on time. Until whenever, take care, and . . . .
