Daniel sez, "Ugo Serrano is the greatest living armorer, really. A man who camps at the Pennsic war in a 15th Century Italian villa (hat he built/designed that also flat-packs for storage and transportation). The props he makes for the movie/television industry are a who's who of geekdom from Firefly to Riddick to the Haunted Mansion through Zorro. A man whose art helped begin the entire steampunk movement, yet he's almost unknown outside of the SCA, where his themed parties are as legendary as his tent. If you catch him at the right time, he'll give you a pilgrimage badge that he cast in pewter by hand, just for taking the tour.
Update: In the comments, Chris Gilman sez, "I would like to correct the above artical. Ugo is a talented guy and love him dearly, but I built and own the Italian house and if you catch me at the right time, I will give you a pilgrimage badge, made by Robert MacPherson, who in my opinion is the greatest living armourer."
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
