I'm still waiting for an AR-style app which overlays the image from your phone camera with points of interest or GPS co-ordinates of distant places. Or hell, even just a map where you can turn your phone facing a general direction and see an approximate line of sight.

"""One of the first attempts to initiate the geotagging aspect of searching and locating articles seems to be the now-inoperative site Wikinear.com, launched in 2008, which showed the user Wikipedia pages that are geographically closest to one's current location.
The 2009 app Cyclopedia works relatively well showing geotagged Wikipedia articles located within several miles of ones location, integrated with a street-view mode, and 360-degree mode."""
