The hop program generates real plane fractals as described in the
September 1986 issue of Scientific American.
hopalong accepts the following options:
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
-mono If on a color display, pretend we're on a monochrome display.
Install a private colormap for the window.
Specify which visual to use. Legal values are the name of a

How many colors should be used (if possible). Default 200.
The colors used cycle through the hue, making N stops around
the color wheel.
How long to run each batch. Default 2500 pixels.
How many pixels should be drawn before a color change. Default
Whether to use the Jong format (default is to choose randomly.)
Whether to use the Sine format (default is to choose randomly.)
-fps Display the current frame rate and CPU load.
DISPLAY to get the default host and display number.
to get the name of a resource file that overrides the global
resources stored in the RESOURCE_MANAGER property.
