The document discusses various examples of graffiti art found in Brazil and overseas that the author finds more beautiful than typical graffiti or tagging seen in the United States. It shares photos from an "Art Less Pollution" installation in Sao Paolo with a message about pollution killing, as well as a series called "Metabiotica" by the same Brazilian artist. The author prefers graffiti abroad that involves local communities and gives a positive sense of belonging, unlike many American tags that are just initials.
