At the inauguration, Microsoft is going to help make history.  If you saw my earlier posts about Photosynth, you know it has been featured in CSI.  In that episode, the police used it to reconstruct a murder scene from cell phone pictures taken by students at a school function.  In this case, CNN is going to use it to create a Photosynth of the moment of inauguration.  Those attending the event are being asked to submit their photos of the moment President Obama is sworn into office.  Assuming that even half of the people (millions are expected) attending the event submit a picture, this will be a HUGE Photosynth.  It will also be an incredibly historic one!  You can read all about it here.
