Title: Petals

There is only one attractor, with period 6, for this Matchmaker Julia set, but there are parameter values close by for which there is a second. As a result, the basin is broken up by large regions of chaos that contain areas of higher iteration that resemble a disconnected classic Julia set. Essentially, the Julia set is that classic one, except extended to also bound the six-petaled structure of the attractor's basin, where the classic one has only one petal to bound as the sole attractor there is a fixed point.

The single basin is colored with a gradient, from white to purple to yellow, orange, red, and black, by smoothed iterations (computed as described for Dragon II (http://www.fractalforums.com/images-showcase-(rate-my-fractal)/dragon-ii/)).

As with all of these images, the actual maximum iterations setting was higher than the reported number; here I used 10,000 but the highest iteration to actually appear in the image was 100.

The slow calculation is a consequence of the very aggressive antialiasing, unfortunately a frequent requirement to do justice to Matchmaker Julia set images.
