The Atlantic says a new moviemaking fad is sweeping South Korea:

ScreenX extends the movie onto the sidewalls of the theater, effectively wrapping certain scenes around the audience by filming in 270 degrees. SoundX was also developed to complement the visual technology and convey a richer sense of space and distance. These inventions provide a way to surround viewers more fully, but more enticingly, they also may offer new narrative possibilities for filmmakers.

Earlier this year, Microsoft presented an XBox project called Illumiroom, which projects the action outside the edges of the TV. The point of the Illumiroom and ScreenX doesn't seem to be enlarging your focus so much as playing with your peripheral vision. It sounds as though ScreenX adds tension to action and suspense screens, by giving you the feeling that danger could be lurking behind you. I imagine it also adds to the thrill of chase scenes when you can see things whipping past your head out of the corner of your eyes. This is a gimmick for sure, but it's a gimmick that could be really dazzling.
