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] [-duration secs] [-fps]
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.
OPTIONS
bumps accepts the following options:
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
-mono If on a color display, pretend we're on a monochrome display.
-install
Install a private colormap for the window.

-duration seconds
