Hi all,<div><br></div><div>I&#39;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 &quot;M-set&quot; of the Burning Ship type?  Has it been found before?  The whole fractal reminds me of a Klingon Bird of Pray, by the way.</div>
