I just can't get out of my mind the idea that something isn't art if all you do is arrange existing objects... Sure, there's plenty of that in the art galleroes of the world, such as the notorious pile of bricks in the Tate. But how is Poser different from a photographer in a studio, arranging the model and some props? It may be that a soft-porn pin-up isn't art, but that has nothing to do with how it was created.
