| FRACTINT The Mandelbrot Set |

| | This **set** is the classic: the only one implemented in many plotting programs, and the source of most of the printed fractal images published in recent years. |

| | Like most of the other types in Fractint, it is simply a graph: the x (horizontal) and y (vertical) coordinate axes represent ranges of two independent quantities, with various colors used to symbolize levels of a third quantity which depends on the first two. |

| | Notice that the boundary of the M-set becomes more and more convoluted (the technical terms are "wiggly," "squiggly," and "utterly bizarre") as the Z-magnitudes for points that were still within the **set** after 150 iterations turn out to exceed 2 after 200, 500, or 1200. |
