I haven't been this excited for a US presidential inauguration since, well, forever! It looks like we will have the event screened in a large conference room at work, so I will try to sneak away to watch part of it.
It's also quite cool to see that PhotoSynth will be used to create a "mash-up" of everyone's photos of the event. CNN will feature a live fly-through of the photos on their "Magic Wall".
Read more about it here, and be sure to send some pictures if you are there!
