🛡️ Wisconsin Crystal Cities

Each wave is a different disaster lineage — blizzard, wildfire, flood, tornado, meteor, glacier. Survivors breed: geometry, size and speed mutate every generation. Fixed towers auto-engage; possess any turret for first-person fire.

Every settlement grows as a mineral: a form (lattice that sets block layout) and a habit (growth shape that sets massing). Population drives block count, height, road tier and traffic. 100 simulated years pass every 60 seconds at 1×.

Corridors upgrade with demand: track → gravel lane → two-lane → four-lane divided → six-lane freeway with medians, overpasses and ramps. Vehicles snap to lane centres, pass slower traffic, and merge at interchanges.

Drop in one or many .glb/.gltf characters. Each becomes a drivable car prim on the map; as cities grow, an emergent number of them spawn as AI drivers using the intercity highways as tracks.

No model loaded

Import GPX, KML, GeoJSON, or CSV (lat,lon[,name]). Points inside the Wisconsin frame become world markers; ordered tracks become a drivable route. You can also drop a live device fix.

No GPS data loaded

60fps canvas capture plus screen/tab capture with audio, PNG stills, clean-HUD shots, and an automatic cinematic director. MP4/H.264 preferred, WebM only as fallback.

Recorder idle

Auto-named PeerJS pilots share position, active turret, aim/fire events, simulation year and chat. The first client becomes the Wake relay; later clients auto-join.
