This is awesome: it is YouTube on acid. It takes any YouTube video and duplicates it in a wall of sequentially updating images. It is hard to explain the complete effect so go watch it. I chose Vivaldi's Winter because of the striking images in the video and the speed at which the images update seems to match the tempo of the music for an extra mesmerizing presence. The site is yooouuutuuube and you can take any YouTube video and apply the same effect.
