Burning Ship FractalTake the recipe for the Mandelbrot set and add one twist: before squaring the number each step, flip both of its parts to positive. That tiny change of sign burns the smooth Mandelbrot bulbs into a jagged skyline that really does look like a ship ablaze on a dark sea.Michael Michelitsch and Otto Rössler named it in 1992. The absolute-value kink destroys the tidy symmetry of the Mandelbrot map, so the edge is no longer a smooth curve anywhere — each mast and rib is a rougher copy of the whole hull.
