DESCRIPTION

14       This  screen  saver  is not meant to look pretty, but rather, to repair
15       burn-in on LCD monitors.
16
17       Believe it or not, screen burn is not a thing of the past.  It can hap‐
18       pen  to  LCD  screens pretty easily, even in this modern age.  However,
19       leaving the screen on and displaying high contrast images can often re‐
20       pair the damage.  That's what this screen saver does.
