+The \fIslidescreen\fP 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
