       This program shows the view of an observer located inside a set of points arranged to a 3D  lattice.   As
       the lattice rotates, various view-throughs appear and evolve.  A simple idea with interesting results.

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.

cubicgrid 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.

       --delaymicroseconds
               How long to pause between frames.  Default is 20000, or 0.02 second.

       --mono  Draw in black and white.  If not used, a fixed all-color scheme is chosen.

       --speednumber
               The maximum speed of the rotation.  The actual speed and axis change smoothly for better  effect.
               0.5 - 10.  The default is 1.0.

       --zoomnumber
               Size  of  the lattice.  Ideally it should fill all the screen, but one may find other values also
               interesting.  5 - 50.  The default of 20 should do for common screen aspect ratios.

       --ticksnumber
               The count of points drawn along every axis.  10 - 100.  The default is 30.

       --bigdots
               Draw the points twice as big.

       --fps   Display the current frame rate, CPU load, and polygon count.

       --symmetrySymmetry
               Which crystalographic symmetry system to use. One of "auto", "cubic", or "hexagonal". "auto" will
               randomly select between symmetry systems.
