Cover Flow is an animated, three-dimensional graphical user interface that is integrated within 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, gestures, or by selecting a file from a list, which flips through the pages to bring the associated image into view. On iPod and iPhone devices, the user slides their finger across the touch screen or uses the click wheel.
Cover Flow was conceived by artist Andrew Coulter Enright and originally implemented by an independent Macintosh developer, Jonathan del Strother. Enright later named the interaction style fliptych to distinguish it from the particular Cover Flow implementation.
Cover Flow was purchased by Apple Inc. in 2006, and its technology was integrated into its music application, iTunes 7.0, which was released September 12, 2006. The name was previously "CoverFlow" without a space.
