        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 config-
        urations (assuming colors) is several tens of billions.


        cube21 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 microseconds
                How long to pause between frames.  Default is  20000,  or  0.02
                Use texture maps.  This is the default.
                Use solid colors.
        -mono   Disable both texture maps and colors.
                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
                Do not spin, showing the same three faces all the time.
        -wander Move the object around the screen.  This is the default.
                Keep the object centered on the screen.
                Shuffle the puzzle randomly at startup.  This is the default.
                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
        -wait number
                How long to stay at ending position after each move.  The mean-
                ing 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
                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.


        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.
