slidescreen - permute the screen image like an 8-puzzle
program takes an image, divides it into
a grid, deletes a random square of that grid, and then randomly slides
one of the neighbors of this "hole" into the hole (and repeat.)
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
for more details.
