MIT movie screen delivers 3D dazzle without the glasses

www.gizmag.com: 3D cinema might bring dinosaur jaws right up to your nose, but it's a wonder the great beasts don't just laugh when they see the oddball glasses on your head that makes the effect possible. A new advancement from MIT takes a well-known trick known as the parallax barrier and leverages it in a way particular to how we move our heads in movie theaters. A small prototype using 50 mirrors and lenses has been developed and, if researchers can advance upon the idea, glassless 3D viewing might just become the future of cinema.
