She is a sculptor. One of her works, titled "Breakthrough," is located at Westminster College, Fulton, Missouri, US. This work features eight sections of the Berlin Wall. Westminster College was the site of Sir Winston Churchill's famous "Iron Curtain" speech in 1946 and is now the site of the Winston Churchill Memorial Museum, housed in the basement of a relocated London church designed and built by Christopher Wren.
Sandys also worked with the Missouri University of Science and Technology, located in Rolla, Missouri, to use a new way to make deep cuts in granite to create the Millennium Arch sculpture which stands across the campus from their Stonehenge monument. The Arch is a single trilithon with a vague silhouette of a man and a woman on each of its supporting megaliths several meters from the arch.
