Send the Warp Your Room people an exact plan for your walls, showing where your doors, windows, pictures, and electrical outlets are, and they'll generate a custom wallpaper for you that "warps" the pattern around everything that protrudes through the paper.

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.
