       The  xmatrix  program  draws  the  2D "digital rain" effect, as seen on the computer monitors in the 1999
       film, "The Matrix".

       Also see glmatrix(6x) for a 3D rendering of the similar effect that appeared in the title sequence of the
       movie.

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.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.

xmatrix accepts the following options:

       --window
               Draw on a newly-created window.  This is the default.

       --root  Draw on the root window.

       --window-idnumber
               Draw on the specified window.

       --install
               Install a private colormap for the window.

       --visualvisual
               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.

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

       --densitypercentage
               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.

       --modetrace
               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.

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

       --modecrack
               Start off by shutting down the power grid.

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

       --modehexadecimal
               Instead of displaying Matrix glyphs, display hexadecimal digits.

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

       --modeascii
               Instead of displaying Matrix glyphs, display random ASCII characters.

       --modepipe
               Instead of displaying random characters, display the output of a subprocess, as ASCII.

       --programsh-command
               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.

               For example:

                    xmatrix -program 'echo Hello World'
                    xmatrix -ascii -program 'ps -eo comm | rev'
                    xmatrix -program 'od -txC -w6 /dev/random'
                    xmatrix -program 'cat /dev/random'
