If you love 360 panoramics then check this out. This is exactly the kind of thing I've been wanting to do when out filming in some spectacular location.
360 panoramics mapped onto each other so you can jump from one view point to another, including 360 aerials. They are viewable in Flash or QuicktimeVR
The Las Vegas one is so immersive I could waste hours just jumping around. If it incorporated a soundscape it would just blow me away.
