Famous Fractals   

San Marco Fractal

The San Marco Fractal is a Julia set which uses the most common formula z = z^2 + c. In the San Marco Fractal, c = -1, or -1 + 0i. When Benoit Mandelbrot found this fractal, its shape reminded him of the San Marco Cathedral whose reflection can be seen in the flooded streets of Venice. That is the only reason why this fractal became more famous than the other Julia Sets.
