Cover Flow is an animated, three dimensional graphical user interface integrated within iTunes, the Macintosh Finder, and other Apple Inc. products for visually flipping through snapshots of documents, website bookmarks, album artwork, or photographs. Cover Flow is browsed using the on-screen scrollbar, mouse wheel or by selecting a file from a list, which flips through dozens of pages to bring the associated image into view.
On iPod and iPhone devices, the user slides their finger across the touch screen or click wheel. Cover Flow was invented by artist Andrew Coulter Enright, and originally implemented by an independent Macintosh developer, Jonathan del Strother.
