When I first saw these orbs, I was almost sure that they we were computer generated. I was wrong. The orbs are a work of art from German Light Art master Bernhard Rauscher (a.k.a. lumenman), and were made using self made plexiglass blades.
I was curious about the perfect orbs, so I reached out to Bernhard to learn how they were made.
The first thing I learned is that those are called Light Planet and not Orbs 🙂
