Here is a fascinating animation video of a medieval Scottish cathedral. Thanks to Alan Torrance for the link.
A recreation of the St Andrews Cathedral as it was in 1318. Today the remains of St Andrews Cathedral only hint at its former glory. The Open Virtual Worlds group at the University of St Andrews, in collaboration with Professor Richard Fawcett from the school of Art History, have used Virtual World technology to create an interactive reconstruction of the Cathedral as it was when first built.
The model is available online. If you wish to explore it for yourself simply create a login and connect to the Apollo grid using a virtual world client.
