Identify this thing, win a $50 gift card

What is it? I thought a thorn or something at first, but now I’m thinking… bee leg? Well, one thing I can say for sure is that it’s a scan by that desktop SEM machine we mentioned a few weeks back. They’re running a contest to win a flash drive and an Amazon gift certificate; all you have to do is go over there and comment what you think is pictured above.

Not exactly a gadget, but I’ll be glad if a CG reader takes home the fitty.
