NAME

        spotlight - move spotlight around desktop
 

SYNOPSIS

        spotlight  [-display  host:display.screen]  [-foreground color] [-back-
        ground 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, grabVide-
        oFrames,  and  chooseRandomImages  options in the ~/.xscreensaver file;
        see xscreensaver-demo(1) for more details.
