NAME

       decayscreen - make a screen meltdown.

SYNOPSIS

       decayscreen [-display host:display.screen] [-window] [-root] [-mono] [-install] [-visual visual] [-delay usecs] [-mode mode]

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, grabVideoFrames, 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.

       -delay microseconds
	       Slow it down.

       -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 perfer 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).
