Austin-based artist Matt Norris makes VERY cool things out of metal (recent pieces in memory include a skeleton pirate sculpture and an amazingly-detailed praying mantis metal sculpture) but one of our favorite things he makes is little brass and recycled bicycle chain pillbugs (or roly polys, where I was raised). Made out of brass you can get them brass-colored or he also makes them with colored patinas. Small enough to fit in your hand but substantial enough to stand out on a shelf or table, at only $40 a piece they are kind of steal for a handmade piece of awesomeness. Find some on his Etsy store (maybe buy a few, because again, they are awesome).
