Sgraffiti is the interactive media façade artwork that forms an expansive collaboration with the existing material graffiti works drawn in this place. When the sun goes down and it gets dark, the images created by code are added to the existing graffiti works, and a new work begins. The elements of fluid and unclear shapes in the image move organically and dynamically, contrasting and harmonizing with the existing graffiti in clear and static forms. The image changes, distorts, and erases in interaction to the movement of the audience in the space and the noise generated by the passage of the train, giving the existing graffiti as a 'still record' with timeliness (Aktualität).
