Small Fractal Exporer (sfe) is a simple Manderbrot set and Julia set generator. You can just click on left side of the screen (in Mandelbrot set complex plane) to choose start seed. The start seed point is value from the Mandelbrot set which is used for Julia set computation. When the point lies in the Mandelbrot set, the Julia set is connected. Otherwise, the Julia set is a Cantor dust of unconnected points. The result is a wonderful picture!
