Hole in Space
In 1980, artists kit galloway and sherrie rabinowitz placed larger than life video displays in new york and los angeles and connected them with a high speed satelite link. Over the next three days, they held the mother of all video chats and proved that size and bandwidth truly do matter in communicating emotion. They called the experiment "Hole in Space".
Here are some clips selected from their video of the event. The file is 17 megabytes. If you are on a slow connection, view the highly compressed Youtube version instead.
