Converting three skateboard planks to act as the blades on an electric ceiling fan is surprisingly straightforward, as Notcot's NOTlabs demonstrates: "staring at the ugly, boring ceiling fan that hung above us led to the idea of of skateboards as fan blades! And sure enough a few days later, skateboards and a nice simple ceiling fan was acquired to test with!"
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.
