Coleco Space Blaster (1978, Lights, 8 D Batteries, Model# 6660)
Huge tabletop style projection game, extremely rare it seems (up until now (Feb, 2004) I wasn't even sure it had ever been produced. Someone sent me an Email with these pictures of the one he received back in 1978). It basically projects a target on the wall, and then you have to aim the gun to shot it. Thanks to William Ochs for sending me the pics!
Do I have this? No.
