DESCRIPTION

14       The  spotlight  program takes an image and exposes small sections of it
15       as if through a wandering spotlight beam.
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-settings(1) for more details.
