National Geographic Digital Media (NGDM) has launched Infinite Photograph, a cutting-edge Web 2.0 photography mosaic application that will allow users to interact with shared online photographs by clicking on color patterns to create an infinite array of stunning mosaics in a variety of themes.

The first Infinite Photograph theme debuted April 15 at www.ngm.com/infinite, featuring mosaics created from user-submitted photos of the natural world as part of National Geographic's My Shot "As Seen on Earth" hub.

An Infinite Photograph digital mosaic is composed of 200 to 500 photographs culled from National Geographic's user-generated My Shot photography database. NGDM will roll out more functionality for Infinite Photograph over the next few months, including features that allow users to select search terms from the entire My Shot database of tagged photos, build Infinite Photographs from their own catalog of digital photography and interact with the program through such social networking sites as Facebook.

"Infinite Photograph taps into avid social media users and photography enthusiasts in a way no Web technology has done to date," said Rob Covey, NGDM's senior vice president of content development and design for online material. "National Geographic has long been known as a leader in stunning photography and for its commitment to preserving our planet. Infinite Photograph supports that longstanding identity and simultaneously represents a significant leap forward into using advanced technology to increase engagement with the brand."
