MonmouthpediA Town.

"Monmouthpedia is the first Wikipedia project to cover a whole town-specifically, the Welsh town of Monmouth. The project aims to cover every single notable place, person, artefact, plant, animal and other things in Monmouth in as many languages as possible, but with a special focus on Welsh. This is a different scale of wiki-project. The project is jointly funded by Monmouthshire County Council and Wikimedia UK, Monmouthshire County Council intend to install free town wide Wi-Fi for the project. Monmouthpedia uses QRpedia codes, a type of bar code a smartphone can read through its camera (using one of the many free QR readers available) that takes you to a Wikipedia article in your language. QR codes are extremely useful, as physical signs have no way of displaying the same amount of information and in a potentially huge number of languages.
Articles have coordinates (geotags) to allow a virtual tour of the town using Wikipedia's mobile apps (or the Wikipedia layer on Google Streetview) and are available in augmented reality software including Layar."
