Collecting....everything

Wow - that's what I call a wall (Apartment Therapy, house in Brooklyn, NY). My future mum-in-law would get a heart-attack if she saw this: "The dust!!" Not sure whether I would create this in my own house (not because of dustofobia though), although it does look quite sophisticated. And if you're a fanatic art and book collector and stuck for wall space, you don't have much choice really do you?
