The relatively young Swindle Magazine (which bills itself as “the definitive pop culture and lifestyle publication” and whose server may be down at the moment) has an article about the history of spray paint, aptly titled “The History of Spray Paint”. The article, while short, reminds us of the that every object trails a history behind it, like the wake that follows a moving boat. The four-dimensional view extends to material culture, too.
Spray paint specifically is interesting because it’s one of a category of objects that allows direct interaction between the user and the built environment, typically for annotation of some sort (benign, artistic, or destructive). Other examples of this category include hand tools (screwdrivers, hammers, etc.) and binding substances (rope, tape, glue, etc.). Maybe someday, cell phones or digital cameras will be able to leave metadata latent in the environment, although you could argue that GPS satellites already do this.
How do we leave our (physical/electronic) mark on the built environment? Possibly related.
