On digging around for the YouTube related to a post in another board, I came across this video for a prototype model of something called "Sixth Sense" The video origin is from a site called TED, which posts video seminars about almost anything and everything about science and technology. I hope you'll be able to watch it in the UK. video is about 8 minutes. Sixth Sense by Pranav Mistry Kind of along the lines of the sci-fi technology of "Minority Report" but this might someday be real, although there may be reasons some will be opposed to it. I'm neutral on it though.
