NAME
     slidescreen - permute the screen image like an 8-puzzle

SYNOPSIS
     slidescreen  [--display  host:display.screen] [--background color] [--grid-
     size pixels] [--ibw pixels] [--increment pixels] [--delay usecs]  [--delay2
     usecs]  [--duration  secs]  [--window] [--root] [--window-id number] [--in-
     stall] [--visual visual] [--fps]

DESCRIPTION
     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,  grabVide-
     oFrames,  and  chooseRandomImages	options in the ~/.xscreensaver file; see
     xscreensaver-settings(1) for more details.

OPTIONS
     slidescreen accepts the following options:

     --window
	     Draw on a newly-created window.  This is the default.

     --root  Draw on the root window.

     --window-id number
	     Draw on the specified window.

     --install
	     Install a private colormap for the window.

     --visual visual
	     Specify which visual to use.  Legal values are the name of a visual
	     class, or the id number (decimal or hex) of a specific visual.

     --grid-size pixels
	     The size of the grid cells.  Default 70 pixels.

     --ibw pixels
	     The size of the "gutter" between grid cells.  Default 4 pixel.

     --increment pixels
	     How many pixels by which a piece should be moved when sliding to  a
	     new location.  Default 10 pixels.

     --delay microseconds
	     How  much of a delay should be introduced between steps of the ani-
	     mation of the motion of each segment.  Default 50000, which is 0.05
	     seconds.  This is closely related to the --increment parameter.

     --delay2 microseconds
	     How much of a delay should be introduced between the end of the mo-
	     tion of one segment and the beginning of  the  motion  of	another.
	     Default 1000000, which is one second.

     --duration seconds
	     How long to run before loading a new image.  Default 120 seconds.

     --fps   Display the current frame rate and CPU load.

ENVIRONMENT
     DISPLAY
	     to get the default host and display number.

     XENVIRONMENT
	     to  get  the  name of a resource file that overrides the global re-
	     sources stored in the RESOURCE_MANAGER property.

     XSCREENSAVER_WINDOW
	     The window ID to use with --root.
