The wonderfully named British town of Staines (there was a Siemens office there where they answered the phone "Hello, Siemans Staines!") has hand-painted road-signs indicating its pedestrian crossings. Each of the crossing peds is a little different, and a Flickr user has compiled a lovely mosaic showing all the different peds around his neighborhood.

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.
