Kublai Khan feels his empire slipping away, and only from the tales of his emissary Marco Polo can he grasp it.  Invisible Cities is a meditation on the nature and form of cities, of both their uniqueness and ubiquity.  This toy theater adaptation of Italo Calvino's novel compresses 18 cities into a menagerie of objects that articulate the narrative, using a variety of mediums including puppetry, object theater, paper mechanics and living sculpture.
