The 3D models have been created from precise three-dimensional photography of 60 of these mysterious objects from the collection of National Museums Scotland.
The intricate spiral and circular patterns chipped into three of its four carved lobes are among the finest examples of Neolithic art.
Among the most famous examples is this entrance stone from the Newgrange passage tomb in Ireland, which is thought to be around 5,200 years old.

But modern archaeologists have determined that the stone balls are much older, created during the Neolithic period (or late Stone Age) around 5,000 years ago, when ancient monuments like this stone circle in Scotland were built.
But the online collection also includes several carved stone balls found at Neolithic archaeological sites in the remote Orkney Islands, off Scotland’s north coast.
Archaeologists think the houses at Skara Brae were occupied from around 3180 to 2500 BC. No one is sure why the village was ultimately abandoned.
