NAME
       decayscreen - make a screen meltdown.

SYNOPSIS
       decayscreen [--display host:display.screen] [--window] [--root] [--win-
       dow-id  number]	[--mono] [--install] [--visual visual] [--delay	usecs]
       [--duration secs] [--mode mode] [--fps]

DESCRIPTION
       The decayscreen program creates a melting effect	by  randomly  shifting
       rectangles around the screen.

       The  image  that	it manipulates will be grabbed from the	portion	of the
       screen underlying the window, or	from the system's video	input, or from
       a random	file on	disk, as indicated by the grabDesktopImages, grabVide-
       oFrames,	and chooseRandomImages options in  the	~/.xscreensaver	 file;
       see xscreensaver-settings(1) for	more details.

OPTIONS
       decayscreen accepts the following options:

       --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.

       --mono  If on a color display, pretend we're on a monochrome display.

       --install
	       Install a private colormap for the window.

       --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.

       --delay microseconds
	       Slow it down.

       --duration seconds
	       How  long  to run before	loading	a new image.  Default 120 sec-
	       onds.

       --mode mode
	       The direction in	which the image	should tend to	slide.	 Legal
	       values  are  random  (meaning pick one),	up, left, right, down,
	       upleft, downleft, upright, downright, shuffle  (meaning	prefer
	       no  particular  direction),  in (meaning	move things toward the
	       center),	out (meaning move things away from the	center),  melt
	       (meaning	melt straight downward),  stretch (meaning stretch the
	       screen  downward),  and	fuzz  (meaning	go  blurry  instead of
	       melty).

       --fps   Display the current frame rate and CPU load.

ENVIRONMENT
       DISPLAY to get the default host and display number.

       XENVIRONMENT
	       to get the name of a resource file that	overrides  the	global
