pr_2-2-2_J_1200_5.jpg Very nice image and colors, Mike!

When I applied Fractint's Evolver to your 3-term 'resistor' formula, I got this grid of thumbnail images: http://www.emarketingiseasy.com/MikeFrazier/M150409G.gif (Click my images for full size.) In the grid of images, P1 varies from -6.16666666 to +6.16666666 in both Real and Imaginary values in X and Y, respectively. The center thumbnail is P1 = (0, 0). Your Dropbox image with P1 = (0, 6.16666666) is the top center thumbnail. When I varied P1 from -8 to +8 in both real and imaginary values, I get this zoomed out grid of thumbnails: http://www.emarketingiseasy.com/MikeFrazier/M150409E.gif which shows a bit more of the parameter space. Here is an area in the parameter space I liked -- taken from near the 3rd thumbnail from the left -- on the X-axis, in the image: M150409E.gif above: http://www.emarketingiseasy.com/MikeFrazier/M150409K.jpg As simple as the formula is: z=0,c1=pixel-p1, c2=pixel+p1, c3=pixel: f1=z*z+c1, f2=z*z+c2, f3=z*z+c3, z=1/(1/f1+1/f2+1/f3), there's tremendous potential in this particular 3-term resistor formula and color map, Mike! Note: I used Richard's "Fractint for Windows beta 5", now called: "Iterated Dynamics," to calculate these images. - Hal Lane (\__/) ######################## (='.'=) # hallane@earthlink.net (")_(") ######################## -----Original Message----- From: Fractint [mailto:fractint-bounces@mailman.xmission.com] On Behalf Of Mike Frazier Sent: Thursday, April 9, 2015 4:16 PM To: Fractint and General Fractals Discussion Subject: [Fractint] pr_2-2-2_J I released a new version of Fracton with a unified user interface and an improved color editor. The fractal I am posting today came from a search I started back in 2012. I was experimenting with a 3 term parallel resistor formula and I tried moving the terms along the imaginary axis instead of the real axis that I usually use. Moving the terms created a lot of interesting parent fractals but one alignment in particular stood out. The colors are from two color maps in Paul Lee's map collection. I used Fracton's new color editor to combine the maps and fit them to the fractal. I liked how the purple areas look like a meandering river.
