The Elder Scrolls games tend to be big, but the universe is even bigger. Please find above an amazing attempt to put all the areas from every game in the series and beyond into one big interactive google maps style app. This is amazing.
It was created by Reddit user Mlendea Horatiu and while he admits it isn't quite the finished article yet, he is looking for feedback for improvements. Not only does it stream online, you can actually download the thing for yourself.
The map contains areas from the series, but also adds places mentioned in the game's lore. This is a seriously awesome undertaking. Easily the coolest thing I've seen today so far.
