Today is a very historic day in the U.S, and Microsoft technology will play a role.
CNN is hosting an amazing project called 'The Moment' at http://www.cnn.com/themoment. Attendees at the inauguration are encouraged to take and send photographs when Barack Obama takes the oath of office. Those photographs will be stitched together into a PhotoSynth capturing the event.
If you're unable to see the event from your current location, you can also see the inauguration broadcast live via Silverlight (and in HD). You can find the Silverlight stream here http://www.pic2009.org/page/content/live.
