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.
