The Cigar Nerds Episode 12: Cogs and Conundrums. This week our nerds dust off their top hats and dive into the world of Steampunk. What the hell is Steampunk? Well, we sit down with the guys from the Ratchet Retrocast and try to figure that out in our intro to Steampunk special. Later we talk with author and radio host Travis Sivart about writing in a Steampunk world. In Science! we talk robot bar tenders, shotgun gardeners, and the end of the world.
