This is some awesome technology.

The software actually takes an unlimited number of images and constructs an interactive, three dimensional (3-D) model of whatever the photographs are of. It also allows people to sync up their photos, and anyone entering meta-data on a similar image will then be added to that person’s image. Thus making every image uploaded, and every meta-tag added to work together. It’s quite amazing. However, they are almost all British. Just kidding.
