In the UK, we have largely built our towns and cities, so a better question might be: 'How could we enhance our cities by overlaying a digital layer?' This layer, spread over the physical, helps us to understand our cities better and create services that allow citizens to interact with the city - and each other - differently.
I've always been a fan of classic films, film making in general has always been magical to me. And nowhere does it's history lie more deeply engrained than Hollywood. I remember watching the That's Entertainment series as a child and being completely entranced by the snapshot into the archives and insights into what happened behind the camera.
