Developed by Apple, QTVR combines photographic images into one 360 degrees view, letting you explore a virtual space without virtual reality peripherals such as datagloves and helmets.
  Actually, you can explore the panoramic environments simply clicking and dragging with the mouse within the movie or by using a couple of keys of your keyboard from within your favourite browser. For example, dragging to the left causes the view to change as if you were turning your head to the left. You can even zoom in on a single stone in a circle for a closer look, or zoom out to see the big picture.
