The World's Smallest Snowman

I grew up in a state that had no snow and moved to one that is pretty much the same so my snowman building skills are severely lacking but I have to admit that I admire the ability to construct this:

You're looking at the tiniest snowman ever built. Well, it looks like a snowman, but this minuscule model — about a fifth the width of a human hair — is not made out of snow. It's constructed of two tiny tin beads that are usually used to calibrate an electron microscope, and welded together with platinum.

It's built by David Cox, a nanotech expert at the Quantum Detection Group of Britain's National Physical Laboratory. He's accustomed to working with such astonishingly small objects, and used his nano-particle manipulation tools to demonstrate the astonishing accuracy of his work.

The remarkable flourish of his smiling snowman is its little happy face, carved into the top orb using a focused ion beam.

Nano anything is sure to pique my interest but I love the artistic flair this scientist gave his creation. It's nice to see the hard sciences influenced by the soft, since I live my life constantly ensconced between the two.
