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


        flipflop  [-display  host:display.screen]  [-visual  visual]  [-window]

        number]  [-spin  number] [-mode sticks | tiles] [-delay number] [-wire-
        frame] [-fps] [-texture]


        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  sec-
        -fps | -no-fps
                Display the current frame rate, CPU load, and polygon count.
                Only draw outlines.
        -texture | -no-texture
                Whether to texture the tiles with a screen grab or an image.


        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.
