Memetic Mutation: The bouncing card deck animation when you win in Microsoft Solitaire.
Older Than They Think: Long before Microsoft made it a computer game, it was already an extremely common solo game and way to kill time, with the earliest recorded versions dating to the 18th century. There was nothing unusual about seeing someone playing a game at his desk or lunch table - using physical cards - during a work break during the 1980s and before. Microsoft's version that first appeared in Windows 3.0 in 1990 was specifically designed to get office workers transitioning from MS-DOS comfortable using the mouse. It was ubiquitous enough to be occasionally referenced in media from the pre-Internet era, often in the form of a passer-by pointing out an overlooked play. Even before Microsoft's versions, there were already implementations of various solitaire games on computers dating back to the mainframe era. One of the first popular computer implementations, Solitaire Royale, was published a few years before Microsoft's version and was ported to several major home computer platforms.
