Aside from just telling you where you are, or letting you point our where you want to be, maps can do a fantastic job of re-contextualising everything you think you know about the world. You probably know that already, but here's a run-down of maps that do it well.
Vlogbrothers does a good job of spinning through some of the more clever map visualisations out there, a fewof which we've seen, but even more we haven't. It's just a quick, whirlwind tour, but you can find links to all the maps in full on the YouTube page. In the meantime, sit back and let your perception of the world shift around you. [Vlogbrothers]
