Colourful Balloon Installation

I joined with some friends for lunch at the Postern Gate (Wetherspoons) in York today. As I set out on my cycle from home the rain started and the cold wind was cutting through me, Once I got my bike safely locked up I did not loiter but hurried under cover. I only noticed this installation as I returned to collect my bike. The Balloon is tethered above Spark in Piccadilly, York.
