Although exhibited nine years ago (1997), the National Gallery of Art in Washington DC has a detailed virtual tour of their Sculpture of Angkor and Ancient Cambodia exhibition. Using VR technology, take a walk through the galleries and click on specific artefacts to get a closer look. You can’t get a really close look, but it’s a good tour to take in the lunchtime.
