TED is an organization which organizes talks which create great ideas. It has the tag-line "Ideas Worth Spreading".

I am a great fan of them and see a lot of videos from their site. Very recently I came across this video about the Pakistan Floods.

Have a look, this was the twitter about the video by its chief Chris Anderson

"The astonishing, beautiful faces of Pakistan's flood victims. Watch, and weep --> http://bit.ly/9kHnhX"

He also has a lot of things about the Pakistan Flood in his blog
