Harmony

Windows Vista has made strides in improving its Windows Explorer interface, but it has yet to integrate anything as dynamic as Apple's Cover Flow. But with a free utility called Harmony, you can add Cover Flow-like browseability to Windows. Harmony works only with iTunes-generated cover art, and it doesn't integrate into Windows Explorer. But it's a simple, free way to add a little Cover Flow-style action to your Windows Media Player experience.
