NAME

       hopalong - draw real plane fractals


SYNOPSIS

       hopalong [-display host:display.screen] [-foreground color]
       [-background color] [-window] [-root] [-mono] [-install] [-visual
       visual] [-ncolors integer] [-delay microseconds] [-cycles integer]
       [-count integer] [-jong] [-no-jong] [-jong] [-no-sine]

       [-fps]


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.
