    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] [-window] [-root]  [-install]
         [-visual visual]
    
    DESCRIPTION
         The slidescreen  program  takes  an  image  of  the  screen,
         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.)
    
    OPTIONS
         slidescreen accepts the following options:
    
         -window Draw  on  a  newly-created  window.   This  is   the
                 default.
    
         -root   Draw on the root 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 1 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  animation of the motion of each seg-
                 ment.  Default 50000, which is 0.05  seconds.   This
                 is closely related to the -increment parameter.
    
         -delay microseconds
                 How much of a delay should be introduced between the
                 end  of  the motion of one segment and the beginning
                 of the motion of another.  Default 1000000, which is
                 one second.
    
    RESOURCES
         On some systems (currently, only SGIs),  this  program  can,
         instead  of  grabbing a desktop image, grab a frame of video
         from an external camera and manipulate  that  instead.   The
         following resources control that.
    
         grabVideoProbability (Float)
                 What portion of the time to grab video rather than a
                 screen image, between 0.0 and 1.0.  Defaults to 0.5,
                 or half the time.
    
         videoDevice (Integer)
                 The number of the  default  video  input  device  to
                 check  first.   If  unspecified,  the default camera
                 (from videopanel(1)) will be checked  first.   After
                 that,  all  other available video input devices will
                 be checked in order.
    
                 The first one which produces a non-black image  will
                 be  used.   If all images are black, the others will
                 be re-checked a few times before giving up and  fal-
                 ling  back  to  simply grabbing a desktop image (but
                 note that this takes a few seconds, so if you  don't
                 actually  have  any  video  sources  hooked  up, you
                 should consider turning off video grabbing  by  set-
                 ting grabVideoProbability to 0.0.)
    
         videoGain (Float)
                 The amount by which to brighten the  grabbed  image.
                 This defaults to 2.2.
    
    ENVIRONMENT
         DISPLAY to get the default host and display number.
    
         XENVIRONMENT
                 to get the name of a resource  file  that  overrides
                 the  global resources stored in the RESOURCE_MANAGER
                 property.
