SYNOPSIS
splitflap [--display host:display.screen] [--visual visual] [--window] [--root] [--window-id number] [--delay microseconds] [--speed float] [--width columns] [--height rows] [--mode text | clock12 | clock24] [--no-wander] [--spin axes] [--no-spin] [--front] [--no-front] [--wireframe] [--fps]

DESCRIPTION
Simulates a split-flap display, an old style of electromechanical sign as seen in airports and train stations, and commonly used in alarm clocks in the 1960s and 1970s.

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.

--window-id number
    Draw on the specified window.

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

--speed number
    Animation speed. 2.0 means twice as fast, 0.5 means half as fast.

--width number
    Columns of the display. Default: 22.

--height number
    Rows of the display. Default: 8.

--mode clock12
    Display a 12-hour clock.

--mode clock24
    Display a 24-hour clock.

--front | --no-front
    When spinning, never spin all the way around or upside down: always face mostly forward so that the text is easily readable. This is the default.

--no-front
    Allow spins to go all the way around or upside down.

--wander | --no-wander
    Whether the object should wander around the screen.

--spin
    Which axes around which the text should spin. The default is "XYZ", meaning rotate it freely in space. "--spin Z" would rotate the text in the plane of the screen while not rotating it into or out of the screen; etc.

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

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

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.

XSCREENSAVER_WINDOW
    The window ID to use with --root.
