Noted graffitiologist Dr. Evan Roth at the Graffiti Research Lab participated in the Graffiti Expo at Fondation Cartier. His process of Graffiti Analysis looks at a “graffiti writer’s unseen movements when creating a tag.” These tag gestures are digitally recorded though motion capture software. Captured motions are archived, visualized and projected; they offer a digital representation of the creation of tags.
