Back in the 1990s, I had the chance to work with a Bubble Panorama photographic system called IPIX that cost thousands of dollars. Today, the same technology from Ricoh does the same thing for only US$399.
@tapsamai, yes but these are panoramic style bubbles as opposed to just a 360 panos. The difference is that you can pan all the way up to the ceiling or the sky with a 360 view. Normal panos allow you to spin sideway within a 360 degrees eye level view.
