What does Mona Lisa need?

According to a recent New York Times "Consumed" column, Mona Lisa needs augmented reality --

One assessment of augmented-reality possibilities suggested a future in which you might point a smartphone at the “Mona Lisa” and access a documentary about Leonardo da Vinci. And maybe someday it will seem normal to look at a Burger King location through a portable screen and see Yelp ratings, diners’ tweets and possibly a character from “Avatar” enjoying a $1 Whopper Jr. Perhaps this will seem advantageous. Why just look at a restaurant, a colleague or the “Mona Lisa,” when you can you can “augment” them all?
