You could remove the top seal of a used light bulb, use a pen/pencil to gently 
break the inner glass tube that holds the tungsten filament. This will give you 
a thin glass container. Now pour clear (distilled) water into it and use it as 
a magnifying lens to project the screen onto a wall.

You may have to turn the brightness of the display all the way up and darken 
the room. Whether it works for you or not, it will be great fun to recycle 
throw away stuff into useful gadgets ;-). Atleast I did, growing up a kid in a 
village in India.
