The National Physical Laboratory (NPL) in the UK has created the world's smallest Christmas card, and at a mere 15 microns wide by 20 microns tall (0.015 by 0.020 millimeters), it out-miniaturizes last season's 30-micron (0.030 millimeter) World's Smallest Snowman. To apply a sense of scale, a human hair is about 50 to 80 microns (0.05 to 0.08 mm) wide.
The microscopic greeting on the 200 nanometer-thick (0.0002 mm) card includes a picture of a smiling cartoon snowman, and the inscription "Season's Greetings", etched into the platinum-coated silicon nitride card using a focused ion beam. "From NPL" is the inscription signed inside the card.
