The Nextwall

Hamburg-based agency Jung von Matt/next unveiled a graffiti wall with embedded interactive qualities.

Billed Nextwall, the 30m-long unit features embedded Semacodes, according to PSFK. Snapping a pic of a Semacode with a cameraphone unlocks hidden videos, mobile wallpaper and social features, like the ability to write to friends on the wall's "digital pinboard."

Passersby can also download an info guide on the wall via Bluetooth. Anyone that snaps a photo of one of the wall's characters can use it as a coupon in nearby shops.
