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.
