I look at it this way, there was nothing I wanted to watch on TV last night and I've learned something new about electric heater design! It also highlights just what a breadth of knowledge there is on this forum, and how helpful (and generally polite) the 'regulars' are on here too. However, I think that should be it for mystery object ID for a while, as I suspect it would very quickly lose its novelty and become tedious.
However, if I had a YouTube account I'd post that bit of night-vision video I have of a cloth moving slightly on an old workbench in a derelict building during a survey I was doing. There was no wind to move it, so it can't have been that... my money is on it being a mouse or a rat, but I couldn't see one on the video footage. That's the only 'unexplained' thing I've ever captured in hours and hours of night vision, camera trap and thermal imaging footage. Plenty of nocturnal animals though, which is just as well as that's what I was looking for!
