Pipe

On my way out for a coffee and a feather duster (my innovation to the cleaning regime), I passed this piece of wall and had to go back for my camera....quite a few looks, I can tell you, as I lined the shot up, unalleviated by the fact I was not dressed as a City building inspector (not that they work in August anyway)!

PS
I'm sure this will be better in LARGE...the detail in zoom on my camera screen was pretty impressive....sometimes I see the 25 million pixels producing the goods.

Apologies for very limited commenting at the moment...Operation Top to Bottom is taking its toll!
