When tastefully created, graffiti is an art form, and not vandalism. Graffiti art tends to give the impression of an individual intrusion into public spaces, claiming a sense of shared ownership. It is personal expression for public consumption, whether you like it or not. The graffiti art on the walls surrounding Bondi Beach, near Sydney Australia was a delightful discovery on my part. The wall stood out in its surroundings. The graffiti was more a contribution than an intrusion, I think. There were some quieter images among the louder ones. I was even fortunate enough to watch an artist at work.
No graffiti? An irony all right.
