Terrax: Walking Fog of War Map

Terrax is a fog of war map for real life. The whole world starts out covered in fog, and it only clears where you actually go, on foot, by bike, by car or by train. So it's part walking game, part step counter, and slowly a map of everywhere you've been. The first week is the fun part. You walk to get coffee and a small hole opens in the fog. You take a different street home just to watch it clear. A few days later your neighborhood has a shape, and you start noticing the gaps: the block behind the grocery store, the park you've driven past for years and never walked into. That's pretty much the whole idea. How it works • GPS clears the map in squares about 80 feet (25 m) wide, and whatever you uncover stays uncovered. • Leave your phone in your pocket with the screen off.
