If you weren't aware of the cartography contest run by Dyson Logos, it's all over now (except for the random "winner's" announcement). There were dozens of people who entered their interpretations of completion for an incomplete map drawn by Dyson...a total of more than 60 entries.
All of those entries are now posted at...
One of mine is included (I've just asked about whether the other entry of mine will be added to the mix).
There is some awesome work among them, some great ideas that I wouldn't have ever thought of. If you want some mapping inspiration, go over and have a look.
