Not tin art, but I have high regard for the many ingenious ways packaging designers can fold together cardboard to make durable and easy to open boxes for a wide variety of products. Conversely, I am perpetually amazed at the many poorly designed "childproofing" mechanisms for pharmaceuticals. As I whip out my pocket knife, I think of the legions of arthritic-handed people wrestling with these monstrosities. I guess we get the bitter with the sweet.
P.S. The Granger pointer dog is my all-time favorite.
