You probably seen what a Cinerama screen looks like. Well, it's curved. And when they show a Cinerama movie in an ordinary letterbox format, some distortion can occur. Some guy came up with this technique called smilebox to try to get the cinerama experience in the living room. I know it's STILL not like cinerama, but it's as close as you can get in the home. I never actually seen a movie done in the smilebox process before. But it'd be kinda interesting if they did that.
