When you think of steampunk — if you ever have — you may envision something along the lines of the novels of Jules Verne: snazzy Victorian suits, monocles and clunky machinery. Apparently, according to the Mark Twain House, the namesake author was also a proponent of this artistic movement. In addition to inspiring works of literature, steampunk has infiltrated fashion, visual art and even the realm of performance art. Starting Oct. 1 all the way through Jan. 15, 2012, the Mark Twain House is presenting the accomplishments of 21 national and international artists who work in the aesthetics of steampunk. Entrance to this event is free with the standard museum admission.
