[--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.
