I have always loved idioms. If you're unfamiliar with them, idioms are seemingly nonsensical phrases that by usage became loaded with meaning-- kill two birds with one stone, once in a blue moon, pot calling the kettle black.
There's an Icelandic idiom, "Það eru margar undur í höfuðkúpu," which translates roughly to "there are many wonders in a cow's head." To my understanding, it's a way to say that the world is crazy.
These landscape photos from Joshua Fuller's trip to Iceland had me pondering the wonders in a cow's head.
