37 Degrees Movie Glasses
Finch, a Sydney-based production company in Australia, has launched 3D-style glasses that allow cinemagoers to watch different versions of the same film, called the 37 Degrees.
The company is experimenting with short films and advertising where you can see a different version of a film by raising or lowering your head. For example, parents could watch a movie next to children who are seeing a toned-down version of the same film.
Finch believes the glasses could also be used for sub-titling, allowing two separate subtitles to be on the screen at the same time, which would make them a favourite for international film festivals.
