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] [-phone number]

The xmatrix program draws dropping characters similar to what is seen on the computer monitors in the Wachowski brothers' film, "The Matrix".

Also see glmatrix(1) 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

Install a private colormap for the window.

-visual visual

Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual.

-delay usecs

The delay between steps of the animation, in microseconds: default 10000.

-density percentage

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 the screen.

-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 to both-mode.

-small | -large These options specify the sizes of the characters. The default is -large.

-trace

Start off with a representation of a phone number being traced. When the number is finally found, display The Matrix as usual.

-phone number

The phone number to trace, if -trace is specified.

-crack

Start off by shutting down the power grid.

-binary

Instead of displaying Matrix glyphs, only display ones and zeros.

-hexadecimal

Instead of displaying Matrix glyphs, display hexadecimal digits.

-dna

Instead of displaying Matrix glyphs, display genetic code (guanine, adenine, thymine, and cytosine.)

-knock-knock

Produce some messages at random times.

DISPLAY

to get the default host and display number.

XENVIRONMENT

to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
