We introduce DigiGraff: a technique to allow lightweight and unconstrained digital annotation of the physical environment via mobile digital projection. Using graffiti as a design meme, DigiGraff provides a way to study the role of location in the creation and browsing of social media, and introduces concepts of temporality, ageing and wear into message presentation. As the volume of geo-tagged social media increases, we outline why such consideration is relevant and important, and how DigiGraff will support deeper understanding of location data in social media.
