Tiny Logos

Fun at McMaster:

Dr. LaPierre's group used a focus ion beam microscope (FIB) to shoot a beam of gallium ions at the surface of a human hair, carving atoms off the of the surface of the hair to etch these McMaster University logos. When not tattooing hair, they'll use the FIB microscope to fabricate nanoscale devices.

Damn!

Come to think of it, I like that. Tattooed hair. It's discreet.
