What mazes there are in this world. The branches of trees, the filigree of roots, the matrix of crystals, the streets her father re-created in his models. Mazes in the nodules on murex shells and in the textures of sycamore bark and inside the hollow bones of eagles. None more complicated than the human brain, Etienne would say, what may be the most complex object in existence; one wet kilogram within which spin universes.
