Seadragon on the iPhone

Microsoft has released it's first iPhone application and its a good one. Some of the more interesting things that are coming out of Microsoft labs are Photosynth and Seadragon, you can see an excellent demo of this at a TED talk from 2007:

In brief Seadragon allows you to zoom quickly and smoothly through a great deal of visual information, so much information infact that when I originally saw the demo I assumed it was a little bit of demo magic being worked on a very high end computer. The zoom interface of Seadragon would seem like a natural fit with the multi-touch interface of the iPhone, but I had always thought that the iPhone did not have the necessary computing power to run such an application, thankfully I was wrong.If you are lucky enough to have an iPhone or iPod check Seadragon out and let me know what you think.
