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
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
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.
