List of Google Easter eggs
In 4.4 (KitKat) a rotating letter "K" appears, which if continually tapped turns into the text "Android" in the styling of a KitKat logo. If the Android logo is then long-pressed a tile interface, known as "a daydream" called "Dessert Case", loads with icons from all previous versions of Android. It appears to be a mock of the Windows Phone interface.
