A Triple Matchmaker Julia set with two attractors. The coloring algorithm used simply applies lighter and darker versions of a shade to alternate iteration bands, and biases the shade further depending on which attractor captures a point. It was actually intended as a "test coloring" that would provide quick one-layer previews of triple matchmaker images while performing "mutational" searches for interesting Julia sets, but in this case it gave nifty, 60s-style psychedelic results and I felt the need to render this fractal with the test coloring. A version with a normal color scheme also exists: Flower Power VI (http://www.fractalforums.com/images-showcase-(rate-my-fractal)/flower-power-vi/).

This fractal also exploits jittering of the pixel coordinates in combination with antialiasing. The results are superior to and faster than with more aggressive antialiasing but no jitter. Here's a comparison:

Antialiasing only
Weaker antialiasing with jitter
