An Austrian camerman is building the Tholos — a pair of panoramic high-definition displays that will be installed at the Eiffel Tower and the Leaning Tower of Pisa, so that the crowd at each can interact with the others in real time. According to a writeup of the project in Reason:

The device, which features a 23-foot wrap-around screen some 10 feet high, works in pairs: People gathered at one Tholos can see real-time, life-size HDTV images of people around a distant partner device, with microphones enabling users to converse. Invented by Austrian cameraman Andreas Traint, the first proposed pair will link Londoners and Viennese in 2004.

Dig the crazee 3D CAD images of a full-sized Tholos, available at the web site of manufacturer Tholos Systems. They look like mirrorshade UFOs.
