Chicago designer Jenny Beorkrem at Ork Posters creates boldly graphic maps breaking cities up into their component neighborhoods using only boundary lines and all-caps typography (DIN 1451, for those who care about these kinds of things). Each map is available in either poster or screen print editions, in a variety of colors.
Right now the choices are limited to Boston, Brooklyn, Chicago, Manhattan, and San Francisco, but apparently Beorkrem's initial run was successful enough that she's quit her day job to focus on this full time.
Of course in musing about what an Ork-style Oakland might look like, I found this map (commissioned by the city in 1982) that the Oakland Museum uses to catalog its collection.
