This group of images is my attempt to duplicate a series of images from a Wikipedia article about the Mandelbrot set. This is image 11 from that series.
I think this image is very close to the version from Wikipedia. The Wikipedia series seems to use fractional iteration counts, since it does not have discrete iteration "bands".
This image was created using FractalWorks, a high performance fractal renderer for Macintoshes. There is a link at the top of this gallery where you can download FractalWorks.
