You know those cheesy scifi conventions where people dress up as Klingons to stand in line for overpriced autographs from C-list has-been actors? Well, I've never been to one despite the fact that I'm a big nerd (and despite writing a story on the subject).

But this weekend I will not only be attending a scifi convention, I'll be an exhibitor. No, really.

I will not, however, be dressing as a Klingon.
