Fourth and final image in the connection

This is not the blip I'd planned - and only works in the context of the connection if you think one size up from the obvious twigs pictured here.

Its been an odd day. OH discovered water leak in garage which judging by the amount had been going for a while. Turns out the overflow from the upstairs toilet empties into the garage! Its a novel way to tell you that a new washer is required...
Anyhow the planned blip required time, which got taken by drying out the garage, and daylight, which again got missed due to clear-up operations.

Answers to the connection tomorrow. I fear even with the answers no-one will get it?!
