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 class, or the id number (decimal or hex) of a specific
visual.
