FOTD -- August 20, 2005 (Rating 5) Fractal visionaries and enthusiasts: When I opened my e-mailbox this morning, I found 11 meaningless letters with 11 copies of the same 79k-byte 'zip' file attached. (One 'zip' file attached to each letter!) It must be some new virus that has just started circulating. We'll see how fast the Earthlink virus filter, which is pretty efficient, starts recog- nizing and deleting it. No deep meaning lies hidden in today's image. It is simply one of the infinite things that numbers do when reiterated. The generating formula is a play on the negative square root of 2, which creates another of those parent fractals that defy exact description. Basically, the parent fractal is a Mandeloid with X-axis symmetry, orientated with the main stem facing east. The large main bay contains two crescent shaped islands, and a circular ring lies at the tip of the main stem. Today's scene is located on the north shoreline of the large bay. To add a bit of interest, I rendered the scene with the outside set to 'real', which colors the pixels according to the value of the real part of the point of escape. The effect is one we have seen several times in recent FOTD's, which is why I rated the image at an altogether average 5. The name "Flanges" came to mind for some reason as I was contem- plating the image in search of a suitable name. Looking at the image today, I see no justification for such a name. A flange is part of a railway wheel, and today's image lies nowhere near the fractal railyard. The render time of 13 minutes is a bit slow for a merely average image. But much time may be saved by visiting the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and downloading the finished GIF image from there. Occasional rain fell through the morning and into the early afternoon Friday here at Fractal Central. The temperature of 75F 24C was quite comfortable, but the fractal cats would rather have been outside. They turned grumpy early and stayed grumpy all day. An extra large treat of tuna in the evening brought them back to a bearable mood. Today is starting cloudy and very muggy. It might turn out too warm for the aging duo. We'll see how the day goes. For me the day will be busy but under control. And the next FOTD will appear in 24 hours. Until then, take care, and don't be one of them.
