This teensy, tiny "snow" man is just one fifth of the width of a human hair.

We put "snow" in inverted commas because he's not really made of snow at all; rather, he's made of two microscopic tin beads.

He was made at the National Physics Laboratory in Middlesex in the UK by Dr David Cox, who likes mucking about with nanofabrication in his spare time.

The snowman was made from two tin beads used to calibrate electron microscope astigmatism. The eyes and smile were milled using a focused ion beam, and the nose, which is under 1 µm wide (or 0.001 mm), is ion beam deposited platinum.

You can see the process of building the snowman in the video below, and more of Dr Cox's miniature sculptures here.
