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.
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific
Time in microseconds to sleep between ticks. Default 25000.
How many ticks should elapse between cycling colors. 0 to dis-
able color cycling. Default 2.
How many ticks should elapse between cycling colors. 0 to use
just one color. Default 1.
How many colors should be used (if possible). Default 32. The
colors are chosen randomly.
Size of each cell, in powers of 2. Default 3 (8-pixel cells).
Percentage of cells that are alive at start and when the field
is repopulated. Default 30.
Maximum age for a cell. Default 64.
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.
