"Tag Clouds"

“Tag Clouds principle is to replace the all-over of graffiti calligraphy by readable translations like the clouds of keywords which can be found on the Internet,” Tremblin describes his project. “It shows the analogy between a physical tag and virtual tag, both in the form (tagged walls compositions look the same as tag clouds), and in substance (like keywords which are markers of net surfing, graffiti are markers of urban drifting)."
