Thanks regine for pointing me on this nice blog about interactive table design! It's about the new incarnation of the dialog table

Like a regular table, Dialog is designed for social interactions, but it utilizes digital technologies and an innovative interface to facilitate learning more about the arts. Gesture recognition and video-tracking software allow multiple users to interact simultaneously with a variety of information appearing on the screen. Using metaphors of water, players can choose artworks by selecting, enlarging, and dragging images from an available "pool" of content to individual "puddles." Connections, represented as threads, are made between artworks, creating links among various pieces and users. Additional information can be obtained about the artwork, including related audio and video clips. Another function allows users to print postcards of favorite works.

This prototype was commissioned by the Walker Art Center through an international design competition in 2002.
