Ali Mazalek's interactive table is nice: tviews1 and tviews2. Made at Media Fabrics Group (MIT Media Laboratory)

TViews is an integrated display and interaction platform designed for collaborative and social exploration of multimedia applications in the home or classroom environment. It can support a variety of interactive applications, including spatial and multi-viewpoint storytelling systems, narrative simulation games, and media content browsing.

An interesting application is the Tangible Viewpoints project which xplores how physical objects and augmented surfaces can be used as tangible embodiments of different character perspectives in a multiple point-of-view interactive narrative.
