A Big Hand

I have been down at Rozelle Park in Ayr this afternoon, attending an exhibition opening in the Maclaurin Gallery. There are lots of sculptures around the grounds including I'm told an impressive World War 1 sculpture trail. This big hand is at the entrance to the gallery and I've no idea what it's all about!
The blurry extra shows a slightly different view.
It is so cold today I am enveloped in multiple layers and I'm still frozen!
