Drawing on the unique cultural resources and experiences of developers around the world, The UN Alliance of Civilizations invites individuals and teams — beginners and experts alike — to create new apps and mobile games that raise awareness and enable new opportunities for intercultural dialogue and submit them in competition for deployment at the UNAOC Forum in Vienna, Austria (27-28 February 2013). After the forum in Vienna, apps will be made available for download so a larger audience may experience what developers contribute to the challenge.
