A fractal drawing from Scientific American, Sept. 85.
Courtesy of Leonard Tramiel. Once the fractal is drawn,
press the space bar to obtain the cursor. You can now
draw a window, using the mouse and button, around any
section of the fractal that interests you. When you release
the button, this section of the fractal will be drawn on
the full screen, so you've essentially got a magnifying
window. This process can usually go 6 or 7 levels deep
(magnifying a piece of a piece of a piece of a piece of
a piece of a piece of the original fractal...) before the
program blows up.
