You are not looking at a human brain. Nor for that matter are you looking at the brain of any living creature. In fact, this is a scanning electron microscope image of a tiny little seed of a plant called rumia crithmifolia.
His images are amazingly detailed, and show off the incredible intricacy of the natural world. Below, though, is my favorite: a picture of a humble strawberry, in all its seedy, hairy glory. Wonderful. [Rob Kesseller via Design Boom; Image by Rob Kesseller]
