World Heritage Tour
I came across this site via my Digital Media World subscription which features a range of QTVRs for world heritage sites. It would be neat to have them add a reconstruction of the places from the same perspective as well - esp as I can see how wonderful they can be via my Visualising the Past course.

Digital Urban Panoramas
Those clever dudes at Digital Urban have been experimenting with embedding panoramas in the QTVR vain into our blogs thanks to flashpanoramas. Their coverage has been through a few updates and the results are well worth a look - will have to see how easy it is to build one myself now.
