NAME

       splitflap - a simulation of a split-flap electromechanical display.

SYNOPSIS

       splitflap  [-display  host:display.screen]  [-visual  visual]  [-window]  [-root]  [-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.

       -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.
