From TED, one of the most incredible technologies I have seen in a long time: Seadragon. It will certainly change the way we interact with digital visual information and will have large impact in the use of photography. The video talk by the author of this software, Blaise Aguera y Arcas -now at Microsoft- is here. If you are using a windows computer you may try Photosynth online with demos of spacial environments using this code.
Blaise Aguera y Arcas created Seadragon (acquired by Microsoft in 2006), the visualization technology that gives Photosynth its amazingly smooth digital rendering and zoom capabilities. Photosynth itself is a vastly powerful piece of software capable of taking a wide variety of images, analyzing them for similarities, and grafting them together into an interactive three-dimensional space. This seamless patchwork of images can be viewed via multiple angles and magnifications, allowing us to look around corners or “fly” in for a (much) closer look. Simply put, it could utterly transform the way we experience digital images.- from TED
