The new app, called "1600" (as in 1600 Pennsylvania Avenue, get it?) allows anyone with a smartphone and a dollar bill to tour the White House in augmented reality. No, the app doesn't cost a buck; instead you use the dollar bill to initiate the virtual tour by pointing the app's camera at it. Announcing the app in a blog post, White House Press Secretary Josh Earnest said:
Today, we're excited to share a new way for you to experience 1600 Pennsylvania Avenue—and all you need is a smartphone and a dollar bill. Check it out now: Download the app, point your smartphone camera at a dollar bill, and you'll see an interactive, 3D video of White House pop up–narrated by yours truly. As you experience a year at the White House–from the Easter Egg Roll to a State Arrival Ceremony–you'll see that even as seasons and people change, the White House endures as an institution of American democracy.
