Have you ever wondered how it feels to be in a photograph? I mean beside the photographer when he or she takes the photograph. To be able look around and feel it. With the latest advance of technology, we it becomes almost possible. There is "Virtual Reality thing".
Rob Galbraith has posted a link to a website with such 360 degree panoramas enabled by VR to look around.
I followed one of the links and found a blog called Refocus, which has underwater panoramas. Take a look - it's a breathtaking view.
