Clayton Boyer makes incredible wooden clocks and clockworks, and sells the plans to build them -- you'll either need some leet woodworking skills, a CAD rig, a laser-cutter, or a lot of willingness to learn.

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.
