Paraphrasing lhetherington's introduction - instead of a traditional 3D flythrough movie he/she decided to use a 3D environment (Secondlife) for presenting the artwork based on data collected from the Torpoint Ferry (Plymouth, UK). This is a 3D abstract data representation displayed in a virtual gallery with the experience of being inside the 3D model.
Physical data has been transformed in to a three-dimensional architectural visualisation, effectively mapping the information as a virtual entity.
For more info take a look at http://www.lhetherington.com
We will be running a feature on using panoramic imagery in Second Life hopefully next week..
