Cool interlude: Human hair tattoo

This isn’t really relevant to much of anything, but I think it’s extremely cool: it’s a “tattoo” — or more of a micro-etching, really — done on the side of a single human hair with a focused ion-beam microscope, by the engineering department at McMaster University in Hamilton, Ontario. The tattoo would be cool enough all by itself, but the fact that my oldest daughter goes to McMaster makes it extra cool 🙂
