The stag is my absolute favourite piece from Sculpture by the Sea. It's just so poetic, from every direction that you look at it. Someone reblogged this image on tumblr and captioned it "expecto patronum". Until reading that comment, I didn't make the connection between the sculpure and Prongs. I loved it even more after that.
Another piece that I really liked is the golden buddha, second from the bottom. The full titles reads "The Golden Buddha's Seaside Holiday". Hilarious! (p/s: My family is Buddhist and I am in no way insulted by it at all.)
