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

SYNOPSIS
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] [-texture]

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

OPTIONS

-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.

-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 seconds.).

-fps | -no-fps
    Display the current frame rate, CPU load, and polygon count.

-wireframe
    Only draw outlines.

-texture | -no-texture
    Whether to texture the tiles with a screen grab or an image.

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.
