Walk it

Uncertainity is a short, experimental browser game — free, no sign-up, a few minutes. It gives you the country you are actually in, as a dark map of its real coastline, and nothing exists until you have been near it. Each day six of the numbers above are hidden in its towns — a different six tomorrow — and a seventh comes from how the world's attention fell on the place today.
