DESCRIPTION
The hop program generates real plane fractals as described in the September 1986 issue of Scientific American.

OPTIONS
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
    Install a private colormap for the window.

-visual visual
    Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual.

-ncolors integer
    How many colors should be used (if possible). Default 200. The colors used cycle through the hue, making N stops around the color wheel.

-cycles integer
    How long to run each batch. Default 2500 pixels.

-count integer
    How many pixels should be drawn before a color change. Default 1000.

-jong integer

-no-jong integer
    Whether to use the Jong format (default is to choose randomly.)

-sine integer

-no-sine integer
    Whether to use the Sine format (default is to choose randomly.)

-fps
    Display the current frame rate and CPU load.

ENVIRONMENT

DISPLAY
    to get the default host and display number.

XENVIRONMENT
    to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
