NAME

       spotlight - move spotlight around desktop

SYNOPSIS

       spotlight    [-display    host:display.screen]    [-foreground   color]
       [-background  color]  [-window]  [-root]  [-mono]  [-install]  [-visual
       visual] [-delay usecs] [-duration secs] [-radius pixels] [-fps]

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.

       spotlight accepts the following options:

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