The Fang of Ladon is a two piece concrete form designed to enclose a mysterious fossilized bone. Like the original animal that it came from, the concrete form cannot function without bones. Oddly shaped, and off-balance, each concrete piece is useless and ungainly on its own. However, when the bone is placed inside, it locks both pieces together in a unified state, allowing the Fang of Ladon to gracefully balance in an upright position.
