This Julia set is from near the center of the blue minibrot prominent in
Fractured Mirror II. As one might expect for a point where the two "interesting" critical points are bifurcating independently, there are two attractors in addition to the omnipresent zero and infinity.
Divergent points get the blue gradient by one layer and points that go to zero get the purple one; both by smoothed iterations. The attractor corresponding to the big
Fractured Mirror ghost-cardioid is in the ring of golden dragons, one point in each in the main chain. This attractor's period is 23. Its basin gets two layers, one
phi-angle layer and one smoothed iterations layer. The final attractor, associated with that blue minibrot, is in disconnected components that are much smaller and connect the chain of dragons. Its period is 69 and its basin is colored using only
phi-angle.<p>
