Every now and again, I stumble across something that makes me 'wow' out loud. Much to the confusion of my fellow bus passengers, no doubt. This was one of those things...
It turns out that a small team of science boffins have been able to create a live (well, as good as live. I think we can live with a 40 millisecond delay) object-cloner for use in video.
I know they use stuff like this in special effects in movies all the time, but seeing it happen right in front of your eyes is a whole 'nother level of magic.
