Signs planted around San Francisco pinpoint exact locations of previous moments of deja vu, and are color coded in relationship to which type of phenomenon occurred there. On each Re:Project sign is a URL and GPS coordinate.
By using a mobile phone, you can text message your location and any relevant information/ description of your experience to the URL provided.
This catalogues your deja vu experience, and connects you to the Re:Project community, where you receive text message notifications of the deja vu phenomenon as they occur around the city.
Each text message includes the location of the occurance and a statment or question, which is meant to challenge your established understanding of the site and provoke a new, or at least different, view of your environment.
Have you experienced Deja Vu? if so, take this survey.
