Looks a little creepy to me. I had visions of Invasion of the Body Satchers or some sort of space-time portal. Actually, that might make a good movie. An itinerat RVer by day, time traveling super hero by night. Going where no man has gone before (groan) I know bad pun.
Seriously, as GRUMPA points out, it is going to get nasty. I don't don't think I would want to change the batteries in it. A stick-on motion sensing light on the wall is how I would go too. And yet anothe pun, sorry..
