I snapped this picture at the Pennsylvania Convention Center at the MLA conference back in December. This Braille sign includes a raised blueprint of the restroom -- but for the sighted, it takes a moment to figure out why you're being given a map. I thought perhaps I was to memorize it in case of fire, use it to guess the location of surprise attackers, or use it to plan my trip to the restroom more carefully.
