Some greek guys did a photostream-video for Sigur Rós album Takk. It's a pretty impressive archive, where users submit their own pics for show in the stream, though I don't quite get the connection with the Sigur Rós music. But Hoppípolla works out fine with landscape snaps or pics of hot babes. Anyways it's nice flashprogramming and a interessting feature. Check it here here.
