This New Scientist video reveals what may be the future of collaboration: a 3-D tabletop display that provides each user their own interactive view. Watch as two users collaborate in a 3-D world; in this case, a virtual city-scape.
Users are able to interact with the display, "without breaking the illusion of depth." And specially-designed 3-D glasses allow each person to see the display from their own unique perspective. Simply amazing.
