I’m approaching the end of a journey which began nearly 3 years ago.  Back then, in summer 2007, I was lucky enough to be directing a film with Stephen Fry about Johannes Gutenberg – the man who invented printing. As we travelled through Germany in quest of that elusive Medieval genius we found ourselves on a twisting road which ran along the sides of the River Rhine.  In the backseat of the crew vehicle Stephen was plugged into his ipod when a mysterious sound filled the van.
