The website nextwall.net features an interactive graffiti wall: the nextwall, which is a creative laboratory that combines street art with digital media. Behind the project is Jung von Matt/next, the Hamburg agency for interactive and innovative communication, and a five-man graffiti crew whose works are known throughout the world: DAIM, for example, was last represented at last yearís Biennale in Venice.

Highlights up to now include:

- The creation of the works of art: for five days live cameras documented the sprayers on nextwall.net as they recorded the history of graffiti on the 30 metre-long wall.

- The Bluetooth information guide: visitors to nextwall are sent all the important information about the artists and the wall directly to their mobile phones.

- QR Codes: they are installed on the wall and can be scanned in with a camera phone. They can be used to load pictures of the wall onto a mobile phone as wallpaper or for immortalizing oneself in a digital visitorsí book.

- Object recognition with a camera phone: anyone who sends an MMS containing a photo of one of the graffiti images to a special number, will receive digital vouchers appropriate to the motif for use in cafÈs and trendy shops in the neighbourhood.

The wall lives on - further highlights are in progress.

All of this is more than just a creative playground: all the technologies will first be tested on the nextwall, then perfected, and later presented to the agency client ñ to be finally used for digital, interactive outdoor advertising.

Whatís in it for the agency? The press and numerous blogs continuously report on the wall and arouse curiosity about Jung von Matt/next ñ in both creative talents and in companies interested in innovative advertising.
