       [--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.

       --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.

       --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.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.
