The World's Smallest Comic Strip Is Etched on a Single Strand of Hair
Even a perfectly smooth human hair looks like a scaly, alien creature under a microscope. Zoom in on this particular hair, though, and you'll find something even stranger: a teeny, tiny comic strip called "Juanita Knits the Planet."
Ten micron-tall Juanita and her friends were etched onto the hair using a focused ion beam. The microscopic comic strip was created for the Exceptional Hardware Software Meeting, a gathering for open source and DIY enthusiasts in Germany.
In case the scaliness of human hair is distracting in the video, here's the whole comic strip, created by Claudia Puhlfürst:
