Gordo - 

You have to put a lens or so in front of it, typically a cylindrical lens.
The LCD is going to be a little dim, and the resolution sucks.  Try a crt
display projected on a visor ala Honeywell, or the Private Eye from Refelct
Tech.  CRT works, is easy and can be done cheap.  The Private Eye resolution
is not that great, but it is usable for a HUD.  I fly with one.
