NAME

       cloudlife - a cellular automaton based on Conway's Life

SYNOPSIS

       cloudlife [-display host:display.screen] [-foreground color] [-background color] [-window]
       [-root] [-mono] [-install] [-visual visual] [-ncolors integer] [-cycle-delay microseconds]
       [-cycle-colors integer][-cell-size integer] [-initial-density integer] [-max-age integer]

       [-fps]

DESCRIPTION

       The cloudlife program draws a cellular automaton based on Conway's Life, except that cells
       have a maximum age, and only one pixel per cell is drawn every tick.

OPTIONS

       cloudlife 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.

       -cycle-delay integer
               Time in microseconds to sleep between ticks.  Default 25000.

       -cycle-colors integer
               How  many ticks should elapse between cycling colors.  0 to disable color cycling.
               Default 2.

       -ncolors integer
               How many colors should be used (if possible).  Default 64.  The colors are  chosen
               randomly.

       -cell-size integer
               Size of each cell, in powers of 2.  Default 3 (8-pixel cells).

       -initial-density integer
               Percentage  of  cells  that  are alive at start and when the field is repopulated.
               Default 30.

       -max-age integer
               Maximum age for a cell.  Default 64.

       -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.
