Pig #05049...

What exactly are things made of? To get a better idea Dutch artist Christien Meindertsma spent three years documenting where every.single.part of pig #05049 went. The end result is a fascinating book illustrating the astonishing range of products this little fellow ended up in. You'll be surprised - hop over here to read more, or here to hear Christien talk about what she found. Note: it's not as gross as it sounds! You can also see more of Christien's art here.
