These amazing photos are from a photographer named Alexandre Duret. He creates spherical panoramas where the photo is shown in 360 and 180 degrees. Really amazing work. I am posting a few here, but do yourself a favor and go see all of them (over 55) on his site. He even lists out step by step directions on how to create them for yourself.
