You'll be pleased to know that Rupert and I were back at work proper today and recorded a new Göbekli Tepe to Stonehenge Podcast. It'll be released both in video and audio versions sometime tomorrow (Friday), all being well.
We've become fascinated by the impact that the trade in obsidian had on the spread of the 'Neolithic Package' and farming from Anatolia across the Aegean sea. It's largely on our minds right now because our next objective for filming 'Göbekli Tepe to Stonehenge' will be to go to Greece and the Cycladic island of Milos to shoot the next stages of the film. It's exciting stuff!
