British Library "Turning the Pages"

I came across the website: British Library "Turning the Pages" the other day http://www.bl.uk/ttp2/ttp1.html

It is an amazing website which has digitized 15 of the Libraries most precious books. What is impressive, is the technology it uses. If you're using Windows Vista and have the "Premium" experience the plug in takes advantage of Direct X9 and all the wizzy graphics stuff. The quality of the images are outstanding and it brings the books to life! If you're unfortunate (or fortunate ) enough not to have Vista then a Silverlight version is available.
