Pop up books are often extremely structurally impressive, to children, because that's who they're intended for. But this one, titled [2,3], from artist Tauba Auerbach is structurally impressive to everyone, and also quite beautiful. The book—technically more a collection of sculptures—comes in six separate sleeves, each with its own structure inside. Many of them incorporate light and shadows, and they all look amazing.
