Orbs are a global phenomenon that has been going on for many years. I found a Dutch orb site with very many pages, and photos going back to the year 2000. You can access it here. I have added it to my list of links to paranormal photos by others, which you can access here.
The Dutch site is multilayered, with some pages having links to many other pages.. The page here shows an amazing photo of a "3D" orb that seems to be halfway behind a physical barrier.
