DESCRIPTION

       This  program  animates  a  puzzle  known  as  Cube  21 or Square-1.  Its moves are chosen
       randomly.

       Cube 21 is a Rubik-like puzzle invented in 1992.  Its specialities are that it can  change
       its  shape  and  even  the  number of possible moves.  It can have more than 200 different
       shapes and the total number  of  configurations  (assuming  colors)  is  several  tens  of
       billions.

OPTIONS

       cube21 accepts the following options:

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

       --root  Draw on the root window.

       --window-id number
               Draw on the specified 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 microseconds
               How long to pause between frames.  Default is 20000, or 0.02 second.

       --texture
               Use texture maps.  This is the default.

       --no-texture
               Use solid colors.

       --mono  Disable both texture maps and colors.

       --wireframe
               Only draw outlines.  Outlines of all pieces, not only the whole object, are drawn.

       --spin  Spin the whole object around X, Y and Z axes.  This is the default.

       --no-spin
               Do not spin, showing the same three faces all the time.

       --wander
               Move the object around the screen.  This is the default.

       --no-wander
               Keep the object centered on the screen.

       --randomize
               Shuffle the puzzle randomly at startup.  This is the default.

       --no-randomize
               Do not shuffle at startup, begin at the shape of cube.

       --spinspeed number
               The relative speed of spinning.  Default is 1.0.

       --rotspeed number
               The relative speed of the moves.  Default is 3.0.  Setting  to  ≤  0.0  makes  the
               object stay at one configuration.

       --wanderspeed number
               The relative speed of wandering around the screen.  Default is 1.0.

       --wait number
               How  long to stay at ending position after each move.  The meaning of the argument
               is again relative.  Default is 40.0.

       --cubesize number
               Size of the object.  Value of 3.0 fills  roughly  all  the  screen  (its  height).
               Default is 0.7.

       --colormode argument
               How many and which colors should the object have.  The colors are put on the piece
               faces so that the puzzle is solvable.  The inner faces are not influenced.

               se or silver
                       Simulate the "Silver Edition" - white and one random color.

               2 or two
                       Two random colors.

               ce or classic
                       Simulate the "Classic Edition" - white, yellow,  orange,  red,  green  and
                       blue.

               6 or six
                       Six random colors.

               1 or random or rnd
                       One random color.

               Anything else
                       All faces white.

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

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_MANAGER property.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.
