Microsoft Labs just released Seadragon for the iPhone (look for the application in the Apps Store).  You may have seen it used in MS Lab’s Photosyth – you can now browse those Photosynth libraries (only in 2d) on your phone.

Download Deep Zoom Composer here and create your own composition.

Check out Blaise Aguera y Arcas TED presentation of Seadragon and Photosynth:
