FOTD -- June 12, 2011 (Rating 6) Fractal visionaries and enthusiasts: Today's image is in two parts, the lower left half and the upper right half. The viewer may choose which half he prefers. The lower left half is intact, while the upper right half is partially evaporated, with the evaporation front running diagonally through the central minibrot. The strange bailout value assigned the imag(p3) parameter controls the position of the evaporation front. The coloring is quite different in the opposing halves. I have worked on the coloring to emphasize the difference, but the result still rates no higher than a 6. The coloring effect in the upper right half was achieved by rendering the image with the inside set to 'zmag'. The other inside fills have varying effects. Actually, the image holds an error. I had intended to enter 8.8 as the value of the imag(p2) parameter, but somehow the decimal point never showed up, and I didn't notice the value of 88 until the image was completed. It was another of those serendipitous accidents that happen so often in fractals. The name "Take Your Choice" implies that the viewer can have it both ways. Those who prefer the lower left half of the image may reduce the bailout a bit and get an entire image like the lower left half. Those who prefer the upper right half may simply increase the bailout. (Setting the inside fill to 'bof61' has the same effect as lowering the bailout.) The calculation time of 4-3/4 minutes is slightly tiresome, but calculation may be eliminated by viewing the completed image on the FOTD web site at: <http://www.crosscanpuzzles.com/Archives.html> A hi-def version of the image is available at: <http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html> The original FOTD web site, which was started in 1997, may be accessed at: <http://www.Nahee.com/FOTD/> A mix of sun and clouds, with a few sprinkles of rain and a temperature of 86F 30C, made Saturday a routine weather day here at Fractal Central. The fractal cats forgot the day even before it began. I took things as easy as possible, aided by FL, who came to the rescue when I showed signs of doing some useful work. In reply, I gave her some morale support when she went to work in her garden. The next FOTD will be posted in 24 hours. My next fractal 'hot' spell is due soon, so check then to see it it has arrived yet. Until next time, take care, and if a physicist should prove that the world is not real. Would he really have proved it . . .
