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.
accepts the following options:
Draw on a newly-created window. This is the default.
Draw on the root window.
If on a color display, pretend we're on a monochrome display.
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.
Display the current frame rate and CPU load.

to get the name of a resource file that overrides the global resources
stored in the RESOURCE_MANAGER property.
