Australian Peter Murphy regularly posts awesome 360 degree QTVR’s on his Panoramic VR Weblog. I find these panoramas to be so immersive! The next best thing to being there. Mr. Murphy has given a lot of thought to 3D panorama techniques, and you can see this in his wonderful results.
Of course, if you like this sort of thing as much as I do, you really should check out Panoramas.dk – in my opinion the ultimate full-screen QTVR site. Gorgeous panoramas like this one, will make you glad you bought that giant LCD display. 🙂
