DESCRIPTION

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

OPTIONS

       rubikblocks accepts the following options:

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

       -root   Draw on the root 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.  Looks a bit weird.

       -mono   Disable both texture maps and colors.  Ditto.

       -wireframe
               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 default.

       -no-spin
               Do not spin, stay in the same tilt 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 0.02.

       -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.

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.
