CoverFlow, the beautiful interface used in iTunes to let users flip through their album art, provides more than just a sleek way to view your albums; it actually provides a very usable and intuitive UI. For instance, CoverFlow on the iPhone just makes sense.

Cover Flow displays all the album art in your music collection in one easy-to-navigate interface that mimics a CD collection or jukebox selection. Move between covers using the forward and back arrows or use the slider to browse faster. When you find what you want, click the artwork to start playing the album.
