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. (Source)

Check out the short video below--and you'll find the comic strip, without the hair, at the link above.
