 In this video they show you how to make a wall projector out of an old LCD and one of those overhead projectors. The video shows the guy taking an LCD monitor apart and removing the LCD itself from the case. He then places the LCD on top of�the overhead projector projection area and tapes it down on the sides. Additionally he adds one small computer fan to the side to keep it cool (though I'm not sure how much good that tiny fan is doing). The end result is what looks like about a 100 inch screen projection on the wall. The whole setup can probably be completed in under $100.
