NAME

       lcdscrub - attempt to repair burn-in on LCD screens

SYNOPSIS

       deluxe   [-display   host:display.screen]  [-visual  visual]  [-window]
       [-root] [-delay number] [-spread number] [-cycles number] [-fps]

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.
