The document discusses the concept of communication 2.0 and perpetual beta thinking, which focuses on unfinished and dynamic solutions using mashups. It provides an example of augmenting physical spaces by blending mediated representations with actual places through a mobile game called "The 23 Skulls" in Vejle, Denmark. The game integrates information from places in the physical city with online information on Flickr, YouTube and Google Maps to create a mixed reality experience for players investigating a conspiracy. The document advocates for using mashups of continuously updated media applications instead of standalone systems to communicate cultural heritage through augmented reality games.
