You may have seen the Cisco TV commercial of video screens in Xi'an, China, and Rome, Italy, that let people interact life-sized in real time. If not, go to www.cisco.com, then click "Expand to learn more." I'm assuming these are real installations, although I can't find anything about them on the web. If they are not real, they should be. Wouldn't it be great if installations like this were set up in town squares around the world -- Tehran, Tokyo, Mogadishu, Calcutta, Denver, Sao Paulo, Baghdad, Dublin, Harare, and so on. On all the time. Once each 24 hours the screens would be randomly rerouted. What fun, for kids especially. What a gift for bringing us all together.
Expensive? A single minute of the war in Iraq ($240,000) would pay for an installation.
