       cloudlife - a cellular automaton based on Conway’s Life

       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.


       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 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

       -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.


       DISPLAY to get the default host and display number.

               to  get  the  name of a resource file that overrides the global
               resources stored in the RESOURCE_MANAGER property.
