It's been a pleasure to share, review and analyze past footage and also learned quite a lot in the process. In this upload there are examples of both rotating orbs and dark rotating shadows with unique shapes observed in association with a main illumination.
The speed the dark shadows are observed moving over the surface is amazing. The shadows also seem like a support for the bright sphere as they move around it and block light.
Both clips filmed in 2011 and by now there are similarities discovered and a better understanding of the bio-mechanical properties and how light plays an important role in communication. History of the event helps to know they are aware of showing the camera and audience presentations of an otherworldly nature.
