Birds, Bows or Angels?

Decided to go to Perth instead of Dundee for the TV cable, which has been successfully fitted now.  Weather was dreary, with drizzle and thick mist all afternoon.

Nearly forgot to take a photo until I was stopped at traffic lights in the centre of town and took a quick shot of some of the pretty Christmas lights through the wet car windscreen.  No idea what they are meant to be, hence the title:-)
