Dave,
If you haven't gotten the January MR, you might want to pick one up. The Beer Line series is starting, and it's another feather in David Popp's cap. He's using a sectional design with modular plan elements that allows the sections to be configured several different ways. In its most basic form it's a big oval, but the modular plan allows it to be "unfolded" a couple of different ways.
This is something I've toyed with over the years, but never had a practical application to carry it forward. Popp does a great job of developing this idea. Truly a man for all seasons...
