"Ethereal culture is grounded, made concrete, in its audience. Works of art in the immaterial domain are never finished, they are simply introduced (initialized) and placed (contextualized) for participation and interaction: the audience may add to, alter, customize, pass on, subtract from the work, etc. The identity or address of the work is therefore shared by the artist and the audience."
-- Tom Sherman, from The Finished Work of Art is a Thing of the Past
