It's trained on moving around dust2, so as long as the previous frame was a view of dust2, the next frame is very likely to be a plausible subsequent view of dust2. In some sense, this encodes a map; but it's not what most people think of when they think about maps.

I'd be interested to see what happens if you look down at your feet for a while, then back up. If the ground looks the same everywhere, do you come up in a random place?
