       flipflop - draws a grid of 3D squares that change positions


       flipflop  [-display  host:display.screen]  [-visual  visual]  [-window]
       [-count number | -free number] [-size number] [-size-x number] [-size-y
       number]   [-spin   number]  [-mode  sticks  |  tiles]  [-delay  number]
       [-wireframe] [-fps]


       Flipflop draws a grid of 3D colored tiles that  change  positions  with
       each other.


       -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

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

       -root   Draw on the root window.

       -count number
               Number  of  tiles on the board. A value of "0" means "default".
               The default number of tiles depends on the size  of  the  board
               and  the  mode:  95% of total tiles for "tiles" mode and 80% of
               total sticks for "sticks" mode (e.g. 76 tiles or 64 sticks  for
               a 9x9 board).

       -free number
               Number of tiles missing from the board. See -count.

       -size number
               Number  of  tiles  on  each side of the board. Takes precedence
               over -size-x and -size-y. Default: 9.

       -size-x number
               Width (in tiles) of the board. Default: 9.

       -size-y number
               Length (in tiles) of the board. Default: 9.

       -spin number
               Angular velocity for the rotation of the board.

       -mode sticks
               Draw hopping sticks instead of flipping tiles.

       -mode tiles
               Draw flipping tiles. This is the default.

       -delay number
               Per-frame  delay,  in  microseconds.   Default:   20000   (0.02

       -fps | -no-fps
               Whether  to  show  a frames-per-second display at the bottom of
               the screen.

               Only draw outlines.


       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.
