Here's a quick video showing how to tie up your laptop (or other boxlike object) such that you can wear it like a messenger bag; it'd be cool to be the guy at the meeting who shows up at a meeting with a coil of rope around his shoulder so that you can go hands-free when it's over.

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.
