Unsurprisingly, it is creative startups that are experimenting most boldly. The Circumstance art collective in Bristol will soon publish a new version of “These Pages Fall Like Ash”, a combination of a print book and an urban-walking app that overlays an imaginary world onto the physical. “Abra” is a fine book and an app that makes poetry magically form and reform. Software developers, meanwhile, are cooking up apps that combine narrative with games. “Gone Home” is a mystery in which the reader/viewer enters an empty mansion and follows clues to unlock text that tells the story of the vanished occupants. In “Device 6“, readers puzzle out a similar mystery chapter by chapter. Such “story exploration games” reveal narrative through gamelike moves, adding graphics to the text-based genre known as interactive fiction (IF).
