This is the first in a series of video reports documenting the progress of The Artvertiser, an urban, hand-held, augmented-reality project exploring the live substitution of advertising content for art.

The footage shows the project in action on the streets of both Berlin and Madrid.

Software is trained to recognise individual advertisements, each of which become a virtual 'canvas' on which an artist can exhibit when viewed through the hand-held device.

The project was initiated by artist and developer Julian Oliver in February 2008 and is being developed in collaboration with artists Clara Boj and Diego Diaz.
