Redditor Volpinazzurra made her own reversible hoodie inspired by the hero of the indie-game smash Journey. Alas, the labor that went into this makes it uneconomical for wider production and sale ("it took me way too long to be profitable!") but Volpinazzurra says she's considering offering the pattern for sale.
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.
