That’s a wild dream, but not a total nightmare. Build a VR mockup first – sketch out the orbital layout, test gravity‑less physics, get a feel for how the pieces move. Then pull the most critical modules out, like the central hub and the life‑support pods, and design them with snap‑in joints so people can actually screw them together. If we keep the components light, maybe carbon‑fiber or high‑strength foam, people can build a tiny version at home. I’ll draft the engineering specs, but we’ll need to keep the kit simple; no micro‑electronics that need soldering unless we want to give the whole project a “DIY” label. Let’s make the city fun to build and a great playground for testing orbital dynamics. Ready to sketch the first block?
