The app of the A Great Experience exhibition records the video-photographing course that a group of seven students with Down syndrome attended in the estate of Castelporziano in March 2013. The exhibition, organized by the General Secretariat of the Presidency of the Italian Republic and set up in the Quirinale Palace, will be inaugurated on the 3rd of December 2013, the International Day of People with Disabilities. The app collects photos and videos made by the students, sheets about the Castelporziano estate and the activities developed during the course. All the materials can be downloaded by unlocking a combination that will be discovered during the visit at the exhibition. With the app it is also possible to follow the work in progress for the setup of the exhibition.
