NAME
       decayscreen - make a screen meltdown.

SYNOPSIS
       decayscreen  [-display  host:display.screen]  [-window] [-root] [-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-demo(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.

       -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
