The writing on the wall

In this case, the entire text of Thomas More's Utopia -written on the old Eastern Electricity building in Norwich in 2006 by artist Rory Macbeth - all 44,000 words.... The building closed in the late 1990s; it was used as an "art outpost" and was pulled down in 2009, taking what was left of Utopia with it. See more photos here.
