In this unusual collection, poems and photographs focus on shapes in nature. Some shapes are found in familiar places: A circle is the sun and a crescent is the moon. But there are imaginative surprises too: an alligator's tooth is a triangle and a frond's shadow forms a square. Related shape words--round, halo, sphere, etc.--are scattered throughout the spreads. This collaboration captures the beauty of shapes in nature in a playful way.
