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 ran-
       domly 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(o) 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.

       -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).
