BBC Scotland News has posed itself the question Public art: What is it for? Regardless of the answer, the article includes a photo of this beautiful sculpture by Andy Scott: Heavy Horse (1997). He's currently working on his giant mythical water spirits The Kelpies (CLICK). I find public art falls into three categories: 1) the artistic, 2) the old pigeon perch, 3) the irritating trendy tripe by some clot who was nominated for the Turner Prize. CLICK for Scotland's answer.
