A colouring book in reverse - instead of colouring in the shapes, you get to fill in shapes with patterns - the mesmerising stripes of a zebra, the tessellating patterns of a turtle's shell, the detail in swirly, spiral ferns. Other activities await as well - try creating your own patterns inspired by the incredible shapes you find in nature. Each page carries information on why these extraordinary patterns exist in nature, whether it's for camouflage, to attract a mate, or for defence.
