The glmatrix program draws the 3D "digital rain" effect, as seen in the
title sequence of the Wachowski brothers' film, "The Matrix".
Also see xmatrix(6x) for a 2D rendering of the similar effect that

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.
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific

How fast the glyphs should move; default 1.0. 2.0 means twice
as fast, 0.5 means half as fast.
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.
