"Screens are (semi-permeable) membranes through which something might pass, but they can also keep something out: they act as sieve and filter. They are rigid and solid, but they can also be movable and flexible. Screens hide and protect, but they also open up and reflect. Screens are in effect something that stands between us and the world, something that simultaneously protects and opens up access."~Elsaesser & Hagener
