In this series I embedded authentic graffiti sentences in the source code of my pictures which sentences appear as visual errors due to the fact that the image formats we use don't understand any human language. The pictures were taken on "used to be" graffiti spots, where these sentences were present for ten or more years, but due to constructions or renovations they disapeared by now. That is exactly why I chose this kind of communication. It refers to the absence of the information as well as to the presence of it.
