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.
