North Hall is a strange beast. There is no connection between South Hall, where the main action is, and North Hall (which is physically located accros the street), so you have to walk (gasp!) through a long tunnel like hallway to reach it. And then, you're into WeirdLand.
North Hall is where they hide dirty and shameful secrets, companies offering wacky products, like a mechanical speaker/megaphone for iPod, a church-oriented "worship presentation software"(does it run on the Jesus Phone?) or hand-made fine felt fabric MacBook and iPod sleeves, straight from the 60s
