slidescreen - permute the screen image like an 8-puzzle
slidescreen [-display host:display.screen] [-background color] [-grid-
size pixels] [-ibw pixels] [-increment pixels] [-delay usecs] [-delay2
usecs] [-window] [-root] [-install] [-visual visual]
The slidescreen 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
file; see xscreensaver-demo(1) for more details.
slidescreen accepts the following options:
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
Install a private colormap for the window.
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific
The size of the grid cells. Default 70 pixels.
The size of the "gutter" between grid cells. Default 1 pixel.

to a new location. Default 10 pixels.
How much of a delay should be introduced between steps of the
animation of the motion of each segment. Default 50000, which
is 0.05 seconds. This is closely related to the -increment
How much of a delay should be introduced between the end of the
