Which is why I think this is pretty cool. They didn't just try to do what everybody else does. It certainly looks more like a place people would hang out in than a place where poeple are going about their hum drum days at the office. Maybe it doesn't excite everybody, but I'm pretty sure that covered tubes, high traffic airport carpet, and gallons of white paint would have excited no one. I think the problem with the tunnels has long been that they were so drab and boring. This makes them interesting and different.
