The mobile phone as a digital SprayCan

Since the first appearance of modern man, one trait of human behavior in our interaction with the physical environment appears to be an inherent desire to leave our mark on a particular object or space. 'SprayCan' graffiti that appeared in the 1970s is but a modern extension of this phenomenon, yet it divides communities and generations in terms of how it should be dealt with in terms of either complete acceptance or punitive action. In this paper we present a system that tries to bridge the divide as it both provides writers with a means of tagging their environment, using mobile phones and RFID tags, whilst minimizing the physical effects to the landscape for the communities where it resides.
