Ikea makes a super-cheap, $9 articulated anglepoise knock-off lamp. The articulated arm is a useful for anything lightweight that needs to have an adjustable X- and Y-axis. Instructables user Brianandrewparker shows how to use a blob of Sugru to mount a webcam to the lamp-base and give yourself a nice, adjustable camera. He notes that this would be useful for mounting other things, too.
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.
