       This program animates a puzzle called Rubik’s Mirror Blocks.  The moves
       are chosen randomly.


       rubikblocks 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.  Looks a bit weird.

       -mono   Disable both texture maps and colors.  Ditto.

               Only draw outlines.  Outlines of each piece, not only the whole
               object, are drawn.

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

               Do not spin, stay in the same tilt 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  final  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.

       -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.
