This post-it pad looks like an onion; each textured sheet is slightly different. Peeling a sheet off reportedly feels like taking a slice off a purple onion. The design won the grand prize at the Japanese Kokuyo Design awards.

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.
