Leo Sewell has built everything, from dinosaurs to dogs, using items like corn-holders and campaign buttons. Leo Sewell's art is easy to appreciate and fun to check out. I'd take a stegosaurus made of junk over a pretentious eco-sculpture anytime.
Implications - My favorite of these eco-conscious creations has got to be the Leo Sewell teddy bear, which has such a cutesy appearance that I'm tempted to snuggle with the thing even though it's made from waste. Maybe if you hug it quick enough, the dirt won't rub off on you.
