`This probably wouldn't work well, as you'd have to shift your focus between
`the display and the world.  Try reading something two inches in front of
`you...  True heads-up displays have their focus at infinity, so they are
`easily readable.

	Greetings. And how does the "focus at infinity" work?
	I presume you would need lenses - acrylic as to not
	have 40 lbs on you head? 

	Hey, you might as well explain - I already took the
	LCD out of the TV. Now what?       ;-)
