I figured someone out there would have come up with something for IR. Maybe a club could afford to buy a few ready made pretty buildings and accessories like those!

For a poor HL guy, the make-the-building-yourself out of cardboard, a few balloons, pins and some paint could still have a very active battlefield. The buildings would be re-useable (unless it rains) and a bag of flour would last a long time. Wouldn't you know, all of a sudden my work load has better than doubled - gotta get some time to get to building some prototypes. Another good thing about the cardboard design would be that they collapse for storage and transportation.

Great research work going on here! Keep 'em comming!
