I just want to give my opinion about art:
To me art is something which is beautiful in MY eyes, something someone has been working on, with a certain "thought" behind it.
I absolutely hate those paintings with but a mark on it being called art!
But there always will be people who like those things I dislike, they will call it art when they feel like it is.
I guess the deffinition of art determined by the "big" people(don't know how to say it diffently, people with loud voices?)
