You Are Not Here (.org) is a platform for urban tourism mash-ups. It invites participants to become meta-tourists on simultaneous excursions through multiple cities.
Passers-by stumble across the curious You Are Not Here signs in the street. TheYANH street-signs provide the telephone number for the Tourist Hotline, a portal for audio-guided tours of one place on the streets of another. Through investigation of these points and with or without the aid of a downloadable map, local pedestrians are transformed into tourists of foreign places.
Current walking tours include Baghdad through the streets of New York City and Gaza City through the streets of Tel-Aviv.
