“Walls, trains or house fronts - graffiti need to be sprayed on solid, “real” backgrounds. Doesn’t it? An answer to this is provided by the “Tagged in Motion” project, which builds a bridge between real graffiti art and its virtual depiction. The centre of attention is the graffiti artist DAIM, who co-created the nextwall. Equipped with the appropriate technology, DAIM sprays graffiti into empty space. In a large hall, three cameras using Motion Capturing record DAIM’s position and the movements he executes with a virtual spray can. The assimilated data is shown to him in real time in a pair of video glasses - as free-floating 3D graffiti in space. In this way he can decide how and where to apply his strokes, and via a Bluetooth controller can also determine the colours, strength of brushstrokes and textures of his work.”
