SYNOPSIS

DESCRIPTION

       The  spotlight  program takes an image and exposes small sections of it
       as if through a wandering spotlight beam.

       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.

       -window Draw on a newly-created window.  This is the default.
