No Tom, this was actually a person. In the video I watched him walk across this barn, check the stalls, and return along the same route and exit. In the video you can see the "blob" change dimensions as, presumably, his hands move around while he navigates. I am trying now to figure out 1. what is his light source, and 2. how can I see "through it" to get a picture of him. But, you are definitely on course with cobwebs. It is a barn and we have had trouble with them already, but they had recently been cleaned off before this.
