Scottish experts produce 3D film of Mount Rushmore
Scottish experts have produced the first fly-through 3D animations of Mount Rushmore - America's iconic monument of four former presidents.
The recording allows digital visitors to sweep up the granite cliff in South Dakota and across the sculpted faces.
It also shows the valley behind the heads, known as The Hall of Records, which is inaccessible to the public.
The work was carried out by the Scottish 10 project, led by Historic Scotland and Glasgow School of Art.
