The Caligari FilmTheater in Wiesbaden arranged the "Atlantis Nature and Environment Film Festival" in October 2008. An accompanying campaign should generate awareness and boost visitor numbers. The concept: the biggest interactive Multitouch-Screen in Germany brings pedestrians into contact with nature. A normal display window was transformed into a touch screen, inviting pedestrians to interact by touching the display window and thus immerse themselves in the festivals films. Due to the multitouch function several people can use the application simultaneously.
