NAME
bumps - move distorting spotlight around desktop
SYNOPSIS
bumps [-display host:display.screen] [-foreground color] [-background color] [-window] [-root] [-mono] [-install] [-visual visual] [-delay usecs] [-radius pixels]
DESCRIPTION
The bumps program takes an image and exposes small, dis
torted sections of it as if through an odd wandering spot
light 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.
