What is Art?
It's a highly creative code used by human beings to communicate with human and non-human beings.
What is a Work of Art?
It's a message full of imagination, made of form and content, sent to the world by an Artist. It has its own life. It comes to life only when somebody "reads" it and gives an interpretation to it. It has little to do with the life of the artist: as soon as the artist gives it its birth, the work of art starts speaking its own autonomous language which needs a human being to be read. So the real "Artist" is not who makes it but who reads it and gives life to it.
Who is the Artist?
It's a human being who tries to produce and send a creative and imaginative message to other human beings (including him/her self) using the Art Code. The Artist is also who "re-produce" the Work of Art" by reading it and giving his/her creative and imaginative interpretation.
