The 'CJ CGV' cinema group developed 'ScreenX,' a technology that gives a 270-degree screening experience in the theatre. Reportedly, about 40 cinemas in South Korea are already using this immersive technology.
The effect seems difficult to capture on video, but it looks like there are three individual screens used instead of one for movie-viewing. Instead of looking at a single screen straight ahead, the 270-degree screening experience happens to your left, right and depending where you choose to sit, behind you as well.
Since it is like being completely wrapped up in the action from all sides, this would be an incredibly exciting way to watch a movie -- though this is probably not a great idea for those who are scared of horror movies.
