What he wants to MAKE is an epidiascope. RMS' link is perfect, it describes what I suggested in my reply too.

Here's how one guy did it on the cheap:

He uses the optics from an old copier and CFL bulbs. The brighter the better, though. I'd try to find something with more lumens than a regular CFL.

Old overhead projector optic, if the room is really dark, you might transmit enough light to project something that way, or,  put the optics in a light-tight box, and use a bright light to illuminate the image from the top.
