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


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]


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.


-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.
Draw on a newly-created window. This is the default.
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.
Allow spins to go all the way around or upside down.
-wander | -no-wander
Whether the object should wander around the screen.
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.


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.
