Wedding present for a geeky couple

A little background: next week I'm performing the wedding ceremony for two very good friends. This weekend I'm going to Vegas Comic Con and I went ahead and splurged on the deluxe John Barrowman package. The photo op is MINE but I've also got an autograph ticket. I thought my friends would love something Jack Harkness related and signed by John as a wedding gift but I don't want it to be just a picture with a name on it. So either its got to be some clever thing (that I can get in the vendor room) or have a personalized message. So I need to come up with an appropriate personalization (something more than "best wishes" or "don't kill each other") by this time tomorrow! Suggestions?
