Here is a recent photosphere I shot at Brexton Hotel in Baltimore (http://www.hotelbrexton.com). You can view it below (click, drag, zoom). If that doesn't work use this direct link: https://goo.gl/maps/RQ4cHNsYSNs
Google photospheres can be taken with the Google Camera for android (not available any more) or the Google street view app. You shoot a couple of dozen pictures and Google seams them together. It works very well for larger areas, not so well in close quarters. We use a professional system.
This is one of the hundreds of amazing products provided by Google companies. This area of immersive photography and video is rapidly improving with better equipment (expensive) and better techniques.
The Google photospheres give you a sense of what is ahead.
I have more than 130,000,000 views on Google Maps.
