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.
