“On one hand by turning the machine inside-out its function is completly transparent, on the other hand a strict self-referentiality and ignorance to the viewer is realized. The machine turns away from the visitor and carries out its computations only for itself. Without depending on interaction or requesting it, it goes through its own states endlessly. The results of the computations are sent inwards -into its own center- they are not intended for the viewer. So an interesting paradox appears: while the machine opens up everything it closes it at the same time, as if it has a secret.”
