DESCRIPTION

       This screen saver is not meant to look pretty, but rather, to repair burn-in on LCD monitors.

       Believe it or not, screen burn is not a thing of the past.  It can happen to LCD screens  pretty  easily,
       even  in  this  modern age.  However, leaving the screen on and displaying high contrast images can often
       repair the damage.  That's what this screen saver does.
