NAME
       xmatrix - simulates the computer displays from the movie

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

DESCRIPTION
       The xmatrix program draws dropping characters  similar  to
       the   displays  in  the  Wachowski  brothers'  film,  "The
       Matrix".

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%.

       -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.

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_MAN-
               AGER property.
