10       ground color] [-window] [-root]  [-mono]  [-install]  [-visual  visual]

DESCRIPTION

16       The cloudlife program draws a  cellular  automaton  based  on  Conway's
17       Life, except that cells have a maximum age, and only one pixel per cell
18       is drawn every tick.
19

OPTIONS

21       cloudlife accepts the following options:
22
23       -window Draw on a newly-created window.  This is the default.
24
25       -root   Draw on the root window.
26
27       -mono   If on a color display, pretend we're on a monochrome display.
28
29       -install
30               Install a private colormap for the window.
31
32       -visual visual
33               Specify which visual to use.  Legal values are the  name  of  a
34               visual  class,  or the id number (decimal or hex) of a specific
35               visual.
36
37       -cycle-delay integer
38               Time in microseconds to sleep between ticks.  Default 25000.
39
40       -cycle-colors integer
41               How many ticks should elapse between cycling colors.  0 to dis‐
42               able color cycling.  Default 2.
43
44       -ncolors integer
45               How many colors should be used (if possible).  Default 64.  The
46               colors are chosen randomly.
47
48       -cell-size integer
49               Size of each cell, in powers of 2.  Default 3 (8-pixel cells).
50
51       -initial-density integer
52               Percentage of cells that are alive at start and when the  field
53               is repopulated.  Default 30.
54
55       -max-age integer
56               Maximum age for a cell.  Default 64.
57

ENVIRONMENT

61       DISPLAY to get the default host and display number.
62
63       XENVIRONMENT
64               to  get  the  name of a resource file that overrides the global
65               resources stored in the RESOURCE_MANAGER property.
