        glmatrix - simulates the title sequence effect of the movie


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


        The  glmatrix program draws dropping characters similar to what is seen
        in the title sequence of the Wachowski brothers' film, "The Matrix".
        Also see xmatrix(6) for a 2D  rendering  of  the  similar  effect  that
        appeared on the computer monitors actually in the movie.


        glmatrix accepts the following options:
        -window Draw on a newly-created window.  This is the default.
        -root   Draw on the root window.
                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
        -delay usecs
                The  delay  between  frames  of the animation, in microseconds:
                default 30000.
        -speed ratio
                How fast the glyphs should move; default 1.0.  2.0 means  twice
                as fast, 0.5 means half as fast.
        -density percentage
                The  approximate percentage of the screen that should be filled
                with characters at any given time.  Default 20%.
        -no-fog By default, glyphs are dimmer the farther away they are.   This
                argument disables that.
                By  default,  waves  of  color roll down the columns of glyphs.
                This argument disables that.
        -binary Instead of displaying Matrix  glyphs,  only  display  ones  and
                Instead  of  displaying Matrix glyphs, display hexadecimal dig-
        -dna    Instead of displaying Matrix glyphs, display genetic code (gua-
                nine, adenine, thymine, and cytosine.)
                Just draw boxes instead of textured characters.
        -fps    Display the current frame rate, CPU load, and polygon count.


        DISPLAY to get the default host and display number.
                to  get  the  name of a resource file that overrides the global
                resources stored in the RESOURCE_MANAGER property.
