DESCRIPTION

The bumps program takes an image and exposes small, distorted sections of it as if through an odd 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.
