My son emailed me about this about a year ago and I never did watch it because it sounded far to ‘techy’. But at only 7 and a half minutes, I highly recommend it to you. Its another great video from TED talks. You can hear the audience have their breath taken away as the implications of this short demo of Photosynth and SeaDragon begin to sink in. I really love the bit about it being “something greater than the sum of its parts emerging from the collective memory to form …” and the bit about our photographs “being automatically hyperlinked based on their content”- well take a look yourself.
