I've had co-workers remember, years after interviewing me, that I brought in some little piece of hardware I built to the interview.

I've showed off circuit boards, half-baked Android apps and referenced webpages during interviews. It always helps.

A couple years ago at an interview debrief, the HR guy said, "Oh, the candidate told me that he was writing some kind of software to automate his home. Who would do that? Weird." And every developer in the room looking at each other and saying "and you didn't think to tell us that?"
