Artworlds are mildly choreographed processes that are establishing as artworks not only products but production, research, curating, art making, forms of living. Artworlds are not objects to be exhibited, not performances to be seen, not texts to be read, not research or experiments, not immaterial art, but they can be all of these and more. They don't have a sharp and clear presence, they can be presented as events, as products, as performances, as concepts, as practices, as processes, as artistic identities. Their esthetic effects are somehow always beyond their appearances. They can take different forms in different contexts and still they maintain their internal chaotic coherence of a world. They are artworks as artworlds.
