I made a post recently on how technology was playing a part in the Inauguration in a way that I expect it had not before.  One of the technologies I mentioned was Photosynth and not that people have uploaded their photos there are a number of new Photsynths to be viewed.

Lincoln Memorial Concert – With this one you can zoom all the way down the crowd and end up looking at the people on the stage. 

The Moment – Three Photosynths here capturing the actual moment

Cool as this technology is,  the applications now might not be obvious.  But 10+ years from now,  when kids are learning about this day at school,  its going to make an excellent tool to help them understand the moment,  something that a single photo on its own with no context just cant do.
