Mysterious Pipework

For Abstract Thursday. I haven't seen pipework like this since I used to play Pipe Mania on my Acorn Electron.

A quiet day today, no deliveries. I've been keeping my head down too, as I think we might have woken the neighbours up last night. Our side gate was banging quite loudly in the strong winds. It woke me up at 2am and again at 4am, and probably in between. I hope I have fixed it now.
