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.
