The Secret Door is a passageway to just about anywhere on Earth. Hosted by U.K. window and door replacement company Safe Style, The Secret Door shows the visitor a virtual door you can click on. Then, using Google Street View, you are shown a random place on the planet.
That can be the Great Wall of China or the streets of New York. Or you can take a look inside the White House. If you want to see something else, click on 'Take me somewhere else' on the left side of the screen.
