I love Sugru, the polymer clay that sticks anything to anything and dries to a durable, dishwasher-safe finish. In this little Sugru ad, they demonstrate how using Sugru to stick single Lego bricks to various surfaces turns anything into a mount for anything else. It's really fun, and reminds me of another great Sugru use: sticking a blob of Sugru over a rare-earth magnet and fixing it to a wall or other surface to make a magnetized sticky-point. (via Make)
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.
