NAME

       xmatrix - simulates the computer displays from the movie

SYNOPSIS

       xmatrix  [-display  host:display.screen]  [-window]  [-root] [-install]
       [-visual visual] [-delay usecs] [-density percentage] [-top | -bottom |
       -both] [-small | -large] [-trace] [-phone number]

DESCRIPTION

       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.

OPTIONS

       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 dig-
               its.

       -dna    Instead of displaying Matrix glyphs, display genetic code (gua-
               nine, adenine, thymine, and cytosine.)

       -knock-knock
               Produce some messages at random times.

ENVIRONMENT

       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.
