If you're interested, a map of the Ancient Roman empire with the ability to map out travel routes under various conditions (what month, by what means, if you're an army, if you're using civilian routes or not, etc.). Not really writing-related unless you're writing about Ancient Rome (or can find two cities with the same obstacles between them as two cities in your world), but it's interesting nonetheless.
