Hi all, I've been playing with the Burning Ship fractal type in Fractint. I changed z^2 to z^3 and came up with a version which has x-axis symmetry, though it needs rotating 45 degrees. Is this the "M-set" of the Burning Ship type? Has it been found before? The whole fractal reminds me of a Klingon Bird of Pray, by the way.
