It wouldn't exist in reality, only digitally, but it would include a very specific, very interesting (to me, at least) feature: Wherever you've walked, driven, flown, sailed, trained, etc., the map would record the exact path of the trip and place a red footprint or blue tire mark or a green flight path on the page. So ultimately, you'd end up with a sort of heat map of the precise places you've set foot on this earth (as well as the modes of transportation you used to get there).
What fascinates me most about this idea would be seeing the disparity between the marks placed near your home (naturally a high volume of footprints, tire tracks, etc.) compared to somewhere you've only been once -- like that open field you traveled to and played touch football or a random concert hall on the west coast. It could take hours to explore your own map, and, literally, re-trace your footsteps.
There's bound to be one little speck of a spot that's not filled in on your front doorstep. After all the times you've trekked in and out, you might never have stepped on that one spot. Would you make it your mission to step there after seeing the map? Or let it happen naturally? Or consciously avoid it? Would you set target goals for optimum stepping places? Would you take a different flight from Chicago to Los Angeles just to cross over a state in which you've got no representation? Or would you shun the technology altogether?
I'm sure innovators aren't too far off from being able to design such a map. After all, our every move already is being documented by our phones. But for now, maybe I'll just slap some red paint on the bottom of my shoes and see where that gets me.
