       Creates a world of falling blocks that build up and up.

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.

       To see which block follow-mode is tracking, set the number of block colors to 1.

       topblock-follow-maxColors1

a       Increases viewing X coordinate.

       z       Decreases viewing X coordinate.

       s       Increases viewing Y coordinate.

       x       Decreases viewing Y coordinate.

       d       Increases viewing Z coordinate.

       c       Decreases viewing Z coordinate.

       f       Increases camera location X coordinate.

       v       Decreases camera location X coordinate.

       g       Increases camera location Y coordinate.

       b       Decreases camera location Y coordinate.

       h       Increases camera location Z coordinate.

       n       Decreases camera location Z coordinate.

       r       Increases world rotation.

       q       quit.

--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.

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

       --root  Draw on the root window.

       --window-idnumber
               Draw on the specified window.

       --delaynumber
               Per-frame delay, in microseconds.  Default: 10000 (0.01 seconds.).

       --wireframe|--no-wireframe
               Render in wireframe instead of solid.

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

       --sizenumber
               Size of the base/carpet.

       --spawnnumber
               Likeyhood of a new block being created per frame : 1 high, 1000 very low.

       --camXnumber
               Initial camera X location in the world.

       --camYnumber
               Initial camera Y location in the world.

       --camZnumber
               Initial camera Z location in the world.

       --rotate|-no-rotate
               Add/Remove rotation to/from the animation.

       --no-carpet
               Remove the base/carpet.

       --no-nipples
               Remove nipples on the blocks (also applies to udders) (has no effect in blob mode).

       --blob  Run in blob mode, blocks become over sized spheres.

       --rotateSpeednumber
               Varries speed of world rotation.

       --follow
               Camera follows blocks as they fall instead of camera being semi static (stays with top block).

       --maxFallingnumber
               Maximum number of objects created before recycling occurs.

       --resolutionnumber
               Resolution of tubes, disks and spheres.

       --maxColorsnumber
               Number of different colors available to falling objects.

       --dropSpeednumber
               Varries speed of falling objects.

       --override
               Overrides camera settings and provides a tunnel view.
