Eyes right!

This morning, we decided to have a wee wander across the Forth Road Bridge.
I was amazed that when we looked to our right, we saw this structure.
I can't remember seeing it before so I guess it's there for the festival!!
I had intended going half way then turning back, but to be quite honest, I'm not a great fan of heights and it was rather windy so I suggested stopping before that.
I would have been happier crawling along the bridge-path on the way back but there were other people watching!!
I am writing this on the bus on my way back up north
I've had a fine time in Edinburgh.
