But what constitutes burn-in is a pixel left in an unchanged state for 
an extended period.  It doesn't have to be in a random state, or a state 
different than an adjacent pixel, like in static -- it just needs to 
change.  So if you, say, changed the background color at regular 
intervals that would change every pixel on the screen.  To make it less 
jarring you could use muted colors and fade/gradient them in.  To me 
that would be the most effective and easiest to achieve result -- every 
pixel would change at the same time for the same length of time and 
therefore be more uniform in their "wear" pattern.  Seeing random 
channel changing would be more disruptive (to me) than seeing blank 
color transitions.

Just a thought...
