So, sorry for the totally garbage picture, but my phone camera sucks, and horrible pictures are on brand for this thread anyway. I turned my indoor tree lights on this morning, and to my surprise saw exactly what we were looking at. It's much crisper in person, but you can see 3-4 lights at an angle, and moving about, it looks exactly like that video. If you have a Christmas tree by a window, go try it yourself. The odds these are what I thought they are is high.
