Here’s a cool concept, turning manhole covers into a street-level navigation system that can direct visitors around a new city.

I must admit, when I first saw the shots of the Map Hole concept I thought it was a cute idea but one that would probably never happen. The issue is one of convenience and cost, man holes come in a uniform shape and size for a very good reason, it makes them easy to place and if need be, replace.

However, when advertising is incorporated into the plan, which it has been, it becomes possible to not only make the manhole covers pay for themselves, but also turn a profit. Nice, as long as your manholes aren’t out in the middle of the street.
