Photosynth Outside My Home In London

So I was looking at Scobleizer blog and he blogged about Microsoft PhotoSynth. I tried it out from on the courtyard outside my home in London on the last sunny day on Summer 2008. But are watching a video it looks like can get a lot more complex.

I am going to make a more complex one later, but you can check out my current one at http://photosynth.net/view.aspx?cid=79245027-407b-40b8-85fb-fcd985a123f9
