I have a friend who tried it in college. Here's the thing - Like was said above, you just get a magnifier and mirrors, etc. and hook them up to your TV (my friend had to turn his on end and "build" a little periscope-like projector with a chair, cardboard, and duct tape.
The whole contraption worked. However, they had to put blankets over the windows and have all the lights turned off. Hope that helps. A fun little project if you're in college and have some friends who like to do stuff like this, but if you're looking for something that's actually workable you probably would want to move on.
