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 the displays in the Wachowski brothers' film, "The Matrix".
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%. -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. -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. -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.
