Part of it is the expectation of talking with other engineers about a project we want done. Part of it was being in a situation where I had enough information available readily to my consciousness to ask good questions, notice lots of things, and generally feel perhaps almost as smart as most people (that seem to like me) seem to think I am. I think I made the sales ladies' day by being so excited by the things their software could do, the things their hardware could do, how elegant the hardware was, all the little design details that make something so much easier to use, ... It was nice.
We're looking at automated embroidery solutions, and while they don't seem to exist off-the-shelf, these folks have done them in the past, and their hardware was just... juicy.
