This artwork/prank/pr stunt is fascinating. We take the fantastically complex technology involved in webcam chat for granted, but connect two points by fibre optic cable (I’m assuming that’s how this works!) and then let people look down the “telectroscope” using the naked eye and suddenly the experience becomes magical again…
Update: I just found that CNN has de-mystified the device – it’s actually a ‘conventional’ pair of very high definition webcams.
