National Geographic is partnering with Microsoft Live Labs to create rich three-dimensional spaces of global landmarks such as Machu Picchu, Stonehenge, and the Taj Mahal. The program takes a large collection of photos (of a place or an object), analyzes them for similarities, and stitches them together for a more immersive experience.

We've sent our photographers out to create a few synths for you to play with, and we're working on adding more. We've also chosen many sites around the world—from Arizona's Canyon de Chelly to the ancient city of Great Zimbabwe—for you to populate with your own photos. Submit shots that you've taken on vacation, during business trips, or from your own backyard, and we'll use them to create new synths. You can also send us suggestions of sites to add to the list.

This is new technology, so please have patience as we work through any bugs. If you encounter a problem with the synths, let Microsoft Live Labs know.
