Great List! Love the ideas!
I actually have asked in a real interview what computer games the person likes to play and why. It let's me ask a question that gets down to the person's passion: I'm not going to hire a techy who isn't passionate about computers. And you can gain valuable insights into a person's character when they tell you they love being a pirate in EVE (an MMORPG) vs a miner or a guild member in WoW vs a solo adventurer.
The whole thing is about creativity and trying to break past the initial awkwardness that is ALWAYS present in an initial interview.
