FOTD -- February 19, 2009 (Rating 8) Fractal visionaries and enthusiasts: Today's image is . . . well, it must be something, but I can't think of what to say about it. It resembles four comets whizzing around a tiny minibrot, so I named it "Comets in Flight". The parent fractal combines various negative portions of Z^(-1.111) and Z^(-11.11). This parent is an oversized thing with a huge 'fan' and many interesting but ultimately disappoint- ing areas to check. I rated the image at an 8. I guess I'm just in the mood for swirling comets. The calculation time of under 2 minutes is fast enough to keep things moving right along. But if a traffic jam develops, the calculation may be avoided by going to the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and viewing the finished image there. Wednesday turned into the most unpleasant day of the winter here at Fractal Central, with an all-day combination of snow, graupel, (tapioca snow), ice pellets, freezing rain, and just plain rain, which by the end of the day left about 1-inch 2cm of slush on the ground. The fractal cats took one look outside and curled up beside the big radiator. Being occupied by other things, I did not worry myself too much with the weather. I'll post the next FOTD in 24 hours. Until then, take care, and if you want nothing to worry about, become a nihilist.
