Whoa! For someone that has never attended any live video conference, this really impressed me. Microsoft Office RoundTable, from Microsoft Research. It has 360° panoramic view video, with head-size equalization. That means, it doesn't matter if you sit at the end of the room, or just next to the device, the video will display everyone in similar sizes. And, there is another video view that shows the active speaker. The device will auto-detect the direction of voice, and shows the speaker on the video.
