Haiku-bombing in chalk is about observation, non-permanence and quietly unsettling our usual relationship with place, and perhaps with each other. Of course it's also about getting a bit of a street-art adrenaline rush.
Haiku-bombing is partly inspired by the famous graffito tag eternity that was written in chalk on Melbourne's footpaths in the 1930s, and then later in the streets of Sydney.
