bumps - move distorting spotlight around desktop
SYNOPSIS
bumps [-display host:display.screen]
[-foreground color] [-background color] [-window]
[-root] [-mono] [-install] [-visual visual] [-delay
usecs]
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.
