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-settings(1) for more details.

--window
