So our Heroscape game this weekend is Hunger Games (Catching Fire) based...and this is going to be the foundation of the map.
The cardboard is below the 2nd layer and allows us to rotate the top layer...just like in the movie. So it's going to be freaking legit having a moving map!
Thought ya'll would appreciate it cause we found a symmetrical way to build it so that each rotation is the same distance and consistent, and allows it to rotate smoothly. Let me know if you have any questions or anything. I'll have more pictures this weekend of the finished map.
