I remember attending an Adobe event years ago at the Rotunda in Camps Bay. Presides the tasty snacks and open bar I remember listening to the guy from Why Not Associates based in the UK. The one thing that really stood out for me was the project they did for the coastal city of Morecambe. It was a typographic solution entitled "a flock of words".
Go and view their website here and the "flock of words" is in their environmental link.
