DESCRIPTION

15       The spotlight program takes an image and exposes small sections  of  it
16       as if through a wandering spotlight beam.
17
18       The  image  that it manipulates will be grabbed from the portion of the
19       screen underlying the window, or from the system's video input, or from
20       a random file on disk, as indicated by the grabDesktopImages, grabVide‐
21       oFrames, and chooseRandomImages options in  the  ~/.xscreensaver  file;
22       see xscreensaver-settings(1) for more details.
