RE: Any idea what this is?
I go by the TAPS reasoning about ORBS and thats not an orb. Most "orbs' are reflections, dust, or bugs. Its not free flowing like a few ORBS i've seen. Its not see through, although it is a circular in shape but it doesn't really change shape at all. No way thats an ORB.
Bigwhitetail an ORB is a collection of energy that most people associate with paranormal activity such as ghosts, spirits, hauntings etc. They beleive spirits manifest themselves by transferring energy from sources and thats what ORBS are, though ORBS are a very discussed topic and many can be explained by weather conditions or camera lens problems.
