An anodized aluminum top and polished stainless steel back. A large, bright display with a lot of pixels per inch. iPod nano stirs up visual effects from the outside in. If a picture says a thousand words, think of what all the album art in your collection might say. With Cover Flow on iPod nano, you can flip through your music to find the album you want to hear. Use the Click Wheel to browse music by album cover, then select an album to flip it over and see the track list.
