Evolving metaphors, in my opinion, is what artists do. They produce work that gives
you the chance to experience in a safe environment, because nothing really happens
to you when you looking at artwork, they give you the chance to experience what
might be quite dangerous and radical new ideas. They give you a chance to step out
of real life into simulator life. A metaphor is a way of explaining something that we've
experienced in a set of terms, a different set of terms.
