What could be a serious case of bad taste turns out to be brilliant!

Had lunch with friends and their garden is wonderful, really a very nice place to be.
Pierro is in the process of making those brilliant sculptures.
From used horseshoes, at first instance this sounds as a clear recipe of bad taste and not very interesting. However, this is a different story he created brilliant objects, with the perfect proportions and a rythme. Really a very nice surprise, to see all those beautiful objects coming out of his hands!
