Pervasive games represent a new trend in organizing of interesting, educational and cultural activities in urban areas. In recent years large cities such as New York, London and Berlin – have organized festivals in which players explore the city through various types and forms of games. These games take place in real space and time, often with the help of technology  -  players use mobile phones, palm top computers, RFID, etc. to solve problems and progress through the game. Although often conducted in open urban areas, these games can be organized in fact anywhere. They are especially suitable content for congresses, conferences and other events where a large number of participants is present. New York’s Come out and Play Festival, London's Hide and Seek, Bristol’s IgFest as well as other festivals in Europe and in the world have a sizeable audience and represent an innovative content that enriches  city’s cultural life. In Belgrade, this kind of game has not yet been organized. ApsArt NVO - Centre for Theater Research in Belgrade is the first organization in Serbia which is engaged in this kind of cultural content.

On the Hide and Seek Weekender festival, the first game produced by the artists group YenDva3 which operates within ApsArt, comprising Bogdan Spanjevic and Mirko Stojkovic was presented.
The game named "Serb.I.Am” is designed so that players through interesting and funny assignments get familiar with four states we used to live in, without leaving Belgrade in previous years: Socialist Federal Republic of Yugoslavia, Federal Republic of Yugoslavia, Serbia and Montenegro and Republic of Serbia. Over a hundred players spent Saturday afternoon on the sunny shore of the Thames in getting to know recent Serbian history and enjoying interesting tasks. In order to take a part in the game, players had to have a mobile phone with a Bluetooth so they could receive tasks. The low-tech version of the game was also provided.

In order to organize these games ApsArt, along with the company SDD ITG has designed special hardware. This is so-called terminal for pervasive games which, when activated with a special play card or bracelet, sends digital content to a player’s mobile phone. This way, the player can receive and review audio or video file on his telephone, as well as related instructions that are in it and then continue the game.
