Imagine standing at the Eiffel Tower and being able to see messages and videos overlaid through your smartphone from all visitors who have come before you. A new app called Wallit combines augmented reality, a virtual view of the real world that can be extended with graphics and other content, with a social experience.

It allows users to post and view content at virtual walls in popular places, tourist attractions such as the Eiffel Tower, stadiums and stores.

“Think of a virtual wall on the face of the Golden Gate Bridge from one end to the other where people can leave sentiments, photos, movies and even audio that are persistent at that location, even though the people who generate the content constantly keep changing,” said Veysel Berk, the founder of Wallit.

The goal, he said, is to record a cumulative, human experience at a location that exhibits the character of a place over time.
