The attractors for this system are made up of line segments which overlap to form an equilateral triangle. Which attractor a point is eventually pulled into is extremely sensitive to its initial position. A very slight change in any direction may cause it to end up on a different attractor. As a result, the basins are thoroughly intermingled. The effect appears to be a frothy mixture that has been subjected to lots of stirring and folding.
Pixel color is determined by which attractor captures the orbit.
The shade of color is determined by the number of iterations required to capture the orbit. In Fractint, the actual shade of color used depends on how many colors are available in the video mode being used. If 256 colors are available, the default coloring scheme is determined by the number of iterations that were required to capture the orbit. An alternative coloring scheme can be used where the shade is determined by the iterations required divided by the maximum iterations. This method is especially useful on deeply zoomed images.
