Here's a link to a cool website that has an awesome panoramic photo of Barack Obama's Berlin speech from within the crowd. The hi-res photo on the website allows you to zoom in and pan 360 degrees. And it has natural sounds of the the people around the camera reacting to Obama's words.
One thing that's notable in the photo is the number of people holding digital cameras taking photos of the event. Everyone wants to record their own little historic moment, and Barack Obama speaking in Berlin is certainly that.
