     color]  [--window] [--root] [--window-id number][--mono] [--install] [--vi-

     [--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.

     --window-id number
	     Draw on the specified 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  re-
	     sources stored in the RESOURCE_MANAGER property.

     XSCREENSAVER_WINDOW
	     The window ID to use with --root.
