The book trees are called 'lifecycle'. They are made from folded recycled books, every page folded identically until the book curls around back onto itself to create these unique geometric shapes. They are then stacked on top of each other to form a totem shape.
The concept is that books are initially made from trees and it's about closing that life cycle and growing them back into a tall, textured, tree form.
They mirror the intricate simplicity of the natural world.
