"I could imagine having virtual sex in Second Life for example, which might be very interesting. Erm, so I'm looking forward to... some progress in the technology and I'm glad that people are already doing Second Life because the technology improvements won't happen unless the first steps are, are err... taken."
Prof. Richard Dawkins (6m14s-6m42s).
It's just as well there isn't a God, Richard.
I like the cheeky look just after he realises what he's just said at 6m40s. In all seriousness, Prof. Dawkins here suggests using head tracking with stereoscopy in Second Life which is something we've been working on recently at University of Derby. I'll be reporting results from these studies soon.
Here's a link to Richard's latest book in case there is a God or anyone from the Royal Society happens to read this blog. His website is subtitled 'A clear-thinking oasis' and I agree.
