FOTD -- July 13, 2008 (Rating 6) Fractal visionaries and enthusiasts: Today's modest effort takes us back to the warhorse formula, the MandAutoCritInZ. I was away from this formula for so long that I almost forgot how it works. After a few minutes trial and error however, my memory was refreshed, and I found today's image in the fractal that results when various negative portions of Z^(-1.6) and Z^(-6) are combined and (1/C) is added. The parent fractal is a string of four large north-south oriented bays, with today's image located just inland from the western shoreline of the southernmost bay -- the bay with the shoreline that most closely resembles the shoreline of the M-set. The scene lies in a field of scattered and disconnected debris. The character of this debris is reflected in the patterns of today's image. I named the image "Back to Basics" because it is a return to the basic workhorse formula. I rated it at a 6 because I think it's worth no more. The calculation time of 20 seconds is blessedly brief, as is the trip to the FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> to view the pre-calculated image there. But due to the unusual hour of this posting, give Paul a chance to get the image up. Saturday here at Fractal Central was on the hot side, but the temperature of 91F 33C was made bearable by a moderate breeze and humidity that was not too high. The fractal cats spent much of the afternoon playing with a few japanese beetles that some- how got inside. After clearing the beetles from FL's roses and giving the plants a good spraying, I had an acceptable day. The next FOTD, good or bad, will be posted in 24 hours. Until then, take care, and if the world is not really out there, then where is it?
