A novel released in 1500 word segments each day through an iphone application. Part of the work can only be read if physically in the geolocation which coordinates with the text.

They are written in relation to the surroundings which they are placed, so the reader is getting visual cues by the setting. By Matthew Derby. He is also the senior interface designer for Harmonix.
