NAME

cloudlife - a cellular automaton based on Conway's Life

SYNOPSIS

cloudlife [--display host:display.screen] [--foreground color] [--background color] [--window] [--root] [--window-id number][--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.

--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.
