Mandelbrot set. Program download. Postcardware. For people who are fascinated with the infinite detail in four dimensional space. With this program you can investigate not only the Mandelbrot set (a mapping of z » z²) but higher order mappings as well. In addition, you can look at Julia Sets and Fatou Dusts - in mappings of third and fourth order, you can see things that Julia and Fatou probably only ever dreamed of.
