Yesterday evening, Microsoft quietly added the photo displaying app SeaDragon Mobile, its first-ever iPhone application, to the App Store. Could Microsoft Office for iPhone be far behind? Probably not, but this is a start.
SeaDragon Mobile is pretty much a demo of Microsoft Live Labs' photo display platform (also seen in Photosynth). Users can use the app to zoom in on photos with incredible resolution. The app achieves this by storing different resolutions, and shows only the portions needed at any given time.
