There’s something compelling about graffiti, about that urge to self-expression in a public space, reclaiming a sense of ownership and challenging convention. But this collection is not that. It’s something altogether smaller, easier to overlook, more mundane in its ambitions.

I wonder when it started this practice of scratching our presence into the world around us? And how, when faced with that clean slate of wet cement, we decide what we want to give of ourselves, how we want to leave our mark?

This is an edited selection of images from this iPhone Collection, made using a mobile phone as a low-tech practice of documenting the everyday and the mundane.
