I've seen a few of these in my travels and think they are excellent, it certainly brighten up an otherwise drab silo. There are many examples of silo art on various sites and I believe there is a site dedicated to following silo art around the country.
I saw that one a while back Hetho. Tumby Bay is a great little town,with lots of art painted on various walls around the town. They give you a little map showing where. Takes less than an hour to walk around to all of them .
