DESCRIPTION

14       The  decayscreen  program creates a melting effect by randomly shifting
15       rectangles around the screen.
16
17       The image that it manipulates will be grabbed from the portion  of  the
18       screen underlying the window, or from the system's video input, or from
19       a random file on disk, as indicated by the grabDesktopImages, grabVide‐
20       oFrames,  and  chooseRandomImages  options in the ~/.xscreensaver file;
21       see xscreensaver-demo(1) for more details.
