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, grabVideoFrames, and chooseRandomImages options in the ~/.xscreensaver
       file; see xscreensaver-demo(1) for more details.
