I've seen them on Wal-mart's website, and with a huge backyard and family, it seems like it would be fun to host a "movie night" a few times during the summer. What I can't understand is how the heck these things work (I haven't purchased one yet, but am wondering if it's even worth it if you have to jump through hoops to get the other things necessary to show a movie on these screens). I'm just wondering how they work. Do you have to buy a special kind of projector for them? And does this mean you have to find reels of the movie you want to watch, or do projectors run on DVDs and VHS, too?
