Graffiti, art or vandalism.

Wikipedia defines art as any activity or product made by human being with an aesthetic or communicative finality, whereby you can express ideas, feelings or your vision of the world, with different elements such as plastics , linguistics, corporal resources. So, is graffiti an art or is it an act of vandalism?.

This is a very controversial issue with different opinions depending on the person you ask. Some consider it as a way to express creativity but others argue that graffiti should be punished. Walking by the city, I can daily see some graffitis ("graffiti" by itself is already plural) in on walls , bridges or facades that are utter art pieces. They express ideas, feelings and a particular vision of the world. Nevertheless, they are not always in the proper place. Some buildings and facades are pieces of art by their own. I neither consider as art a graffiti that covers a train window or traffic signal, nullifying their use. Art should not make life difficult but the contrary.

From my point of view, which could never be considered as art are all the signatures that only try to show that their authors were there and cause a huge cost to the city council and shop-keepers to remove.
