Fred Kahl, a Coney Island performer and magician, is kickstarting a project to put a 3D scanning/printing studio and a 3D printed miniature Coney Island at Coney Island's Luna Park. He's developed a cheap 3D scanner based on a Kinekt, and will release the full plans to Thingiverse once he's fully funded. He's looking for $15K (he's already crested $10K), and $25 gets you scanned in his NY studio ($60 gets you scanned and printed).
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.
