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.
