Steampunk refers to technology that looks and functions as if it was created during the steam era of the 19th century, often involving alternate histories where technological development took a different path. It shares themes of rebellion with cyberpunk but is usually set in a Victorian era setting rather than a dystopian future. Some famous steampunk works include The Difference Engine by William Gibson and Bruce Sterling, The League of Extraordinary Gentlemen by Alan Moore and Kevin O'Neil, and the anthology Steampunk features several steampunk stories.
