xmatrix - simulates the computer displays from the movie
xmatrix [-display host:display.screen] [-window] [-root] [-install]
[-visual visual] [-delay usecs] [-density percentage] [-top | -bottom |
-both] [-small | -large] [-trace] [-mode mode] [-phone number] [-fps]
The xmatrix program draws the 2D "digital rain" effect, as seen on the
computer monitors in the Wachowski brothers' film, "The Matrix".
Also see glmatrix(6x) for a 3D rendering of the similar effect that
appeared in the title sequence of the movie.
xmatrix accepts the following options:
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
Install a private colormap for the window.
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific
The delay between steps of the animation, in microseconds:
The approximate percentage of the screen that should be filled
with characters at any given time. Default 75%.
When running in a window, typing + will increase the density
and typing - will decrease it. Typing 0 will momentarily drain
-top | -bottom | -both
If -top is specified, the characters will only drop in from the
top of the screen as sliding columns of characters. If -bottom
is specified, then instead of sliding columns, the characters
will appear as columns that grow downwards and are erased from
above. If -both is specified, then a mixture of both styles
will be used. The default is -both.
When running in a window, typing [ will switch to top-mode,
typing ] will switch to bottom-mode, and typing \ will switch
-small | -large
These options specify the sizes of the characters. The default
Start off with a representation of a phone number being traced.
When the number is finally found, display The Matrix as usual.
This is the default.
The phone number to trace, if -trace is specified.
Start off by shutting down the power grid.

Instead of displaying Matrix glyphs, display hexadecimal
Instead of displaying Matrix glyphs, display genetic code
(guanine, adenine, thymine, and cytosine.)
Instead of displaying Matrix glyphs, display random ASCII
Instead of displaying random characters, display the output of
a subprocess, as ASCII.
The command to run to generate the text to display. This
option may be any string acceptable to /bin/sh. The program
will be run at the end of a pty or pipe, and any characters
that it prints to stdout will be placed in the feeders for
xmatrix. If the program exits, it will be launched again after
xmatrix has processed all the text it produced.
xmatrix -program 'echo Hello World'
xmatrix -ascii -program 'ps -eo comm | rev'
xmatrix -program 'od -txC -w6 /dev/random'
xmatrix -program 'cat /dev/random'
