Ever wondered what it is like to attend a state dinner at the White House or see Marine One land on the South Lawn? During his eight years as President, Barack Obama has combined traditional events and new technology to open the doors of the White House to more Americans than ever before. In keeping with this commitment, last week the White House team announced a new way for Americans to experience 1600 Pennsylvania Avenue—all you need is a smartphone and a dollar bill. Just download the App (1600), point your smartphone camera at a dollar bill and an interactive, 3D video of the White House will pop-up with narration. The app is available for both iPhones and androids.
