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-settings(1)
for more details.
