DESCRIPTION

18       The  cloudlife  program  draws  a  cellular automaton based on Conway's
19       Life, except that cells have a maximum age, and only one pixel per cell
20       is drawn every tick.
21

OPTIONS

23       cloudlife accepts the following options:
24
25       --window
26               Draw on a newly-created window.  This is the default.
27
28       --root  Draw on the root window.
29
30       --window-id number
31               Draw on the specified window.
32
33       --mono  If on a color display, pretend we're on a monochrome display.
34
35       --install
36               Install a private colormap for the window.
37
38       --visual visual
39               Specify  which  visual  to use.  Legal values are the name of a
40               visual class, or the id number (decimal or hex) of  a  specific
41               visual.
42
43       --cycle-delay integer
44               Time in microseconds to sleep between ticks.  Default 25000.
45
46       --cycle-colors integer
47               How many ticks should elapse between cycling colors.  0 to dis‐
48               able color cycling.  Default 2.
49
50       --ncolors integer
51               How many colors should be used (if possible).  Default 64.  The
52               colors are chosen randomly.
53
54       --cell-size integer
55               Size of each cell, in powers of 2.  Default 3 (8-pixel cells).
56
57       --initial-density integer
58               Percentage  of cells that are alive at start and when the field
59               is repopulated.  Default 30.
60
61       --max-age integer
62               Maximum age for a cell.  Default 64.
63
64       --fps   Display the current frame rate and CPU load.
65

ENVIRONMENT

67       DISPLAY to get the default host and display number.
68
69       XENVIRONMENT
70               to get the name of a resource file that  overrides  the  global
71               resources stored in the RESOURCE_MANAGER property.
72
73       XSCREENSAVER_WINDOW
74               The window ID to use with --root.
75
