I’m a Mac users who’s been desperate to give Photosynth a whirl. It’s always looked absolutely wicked.
Today Microsoft Live Labs got some massive brownie points with the release of their first iPhone app, Seadragon.
Seadragon is the core technology behind Photosynth. It’s designed for zooming smoothly in, out and around photos over the Internet, regardless of bandwidth constraints or image size.
It’s technological trick is to store images in multiple resolutions and deliver only the bits needed to present the view a user wants at any given moment.
Anyway it’s bloody brilliant, make sure you check out the Galaxy and Nebula photography.
Here’s a visualisation from Last.fm:
