30 The \fIxmatrix\fP program draws dropping characters similar to what
31 is seen on the computer monitors in the Wachowski brothers' film,
35 .BR glmatrix (MANSUFFIX)
36 for a 3D rendering of the similar effect that appeared in the title
37 sequence of the movie.
40 accepts the following options:
43 Draw on a newly-created window. This is the default.
46 Draw on the root window.
49 Install a private colormap for the window.
51 .B \-visual \fIvisual\fP\fP
52 Specify which visual to use. Legal values are the name of a visual class,
53 or the id number (decimal or hex) of a specific visual.
55 .B \-delay \fIusecs\fP
56 The delay between steps of the animation, in microseconds: default 10000.
58 .B \-density \fIpercentage\fP
59 The approximate percentage of the screen that should be filled with
60 characters at any given time. Default 75%.
62 When running in a window, typing \fB+\fP will increase the density and
63 typing \fB-\fP will decrease it. Typing \fB0\fP will momentarily
66 .B \-top\fP | \fB\-bottom\fP | \fB\-both
67 If \fB\-top\fP is specified, the characters will only drop in from the
68 top of the screen as sliding columns of characters. If \fB\-bottom\fP
69 is specified, then instead of sliding columns, the characters will appear
70 as columns that grow downwards and are erased from above. If \fB\-both\fP
71 is specified, then a mixture of both styles will be used. The default
74 When running in a window, typing \fB[\fP will switch to top-mode,
75 typing \fB\]\fP will switch to bottom-mode, and typing \fB\\\fP will
78 .B \-small\fP | \fB\-large
79 These options specify the sizes of the characters. The default
83 Start off with a representation of a phone number being traced.
84 When the number is finally found, display The Matrix as usual.
87 .B \-phone\fP \fInumber\fP
88 The phone number to trace, if \fB\-trace\fP is specified.
91 Start off by shutting down the power grid.
94 Instead of displaying Matrix glyphs, only display ones and zeros.
97 Instead of displaying Matrix glyphs, display hexadecimal digits.
100 Instead of displaying Matrix glyphs, display genetic code
101 (guanine, adenine, thymine, and cytosine.)
104 Instead of displaying Matrix glyphs, display random ASCII characters.
107 Instead of displaying random characters, display the output of a subprocess,
110 .B \-program \fIsh-command\fP
111 The command to run to generate the text to display. This option may
112 be any string acceptable to /bin/sh. The program will be run at the
113 end of a pty or pipe, and any characters that it prints to
114 \fIstdout\fP will be placed in the feeders for xmatrix. If the program
115 exits, it will be launched again after xmatrix has processed all the
120 xmatrix -program 'echo Hello World'

122 xmatrix -program 'od -txC -w6 /dev/random'
123 xmatrix -program 'cat /dev/random'
129 to get the default host and display number.
132 to get the name of a resource file that overrides the global resources
133 stored in the RESOURCE_MANAGER property.
