The rotzoomer program grabs an image, then picks
rectangles and draws scaled and rotated animations of that
section.
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.
