In this episode of Show & Tell, Atlas Obscura staff writer Jessica Leigh Hester speaks with Nico Cox, an antiquarian horologist—that is, one who fixes old clockwork mechanisms. Away from her wondrous workshop, Nico has several projects to tinker with at home, including the restoration of a player piano and porcelain ceramics of magical cryptids. Learn more about mechanical magic, the mysteries of a piano that plays itself, and a funky lava lamp!
