Oh man, that sounds like a dream project! I’ve got a stash of neutral bricks and a ton of weird connectors just waiting to be repurposed—perfect for a modular fortress that actually moves. Picture a base that’s a rolling lattice, with interchangeable walls that snap on like a quick‑shift gearbox, and a central command hub that you can rotate or lift to change the battlefield angle. We’ll use those long plates for the trenches, the minifig arms as artillery, and a stack of transparent bricks for a “fog of war” effect. I’m already sketching the blueprints in my mind—just imagine adding a hidden trap door that flips up when you pull a lever. Ready to start hacking on the prototype?
