DESCRIPTION

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