CNN and MSNBC are both launching Photosynth viewers that will help capture the Oath of Office experience. They will combine pictures takes from professional photographers with pictures uploaded from people in the crowd to create an interactive Photosynth experience of the event using Silverlight's built-in DeepZoom feature to deliver an amazing 3D viewing of it.

Check out CNN's and MSNBC's pages a few hours after viewers send in their pictures of the inauguration crowd, the President-elect's raised hand, and everything in between.
