- For
- Space-colony design and orbital-habitat enthusiasts
- Worth noticing
- City, suburbs, farms, parks, and water share one land budget; any land left over becomes farmland.
Field notes
The controls cover habitat geometry, propulsion options, architectural styles, time of day, and a land-use allocation shared across five categories. The page distinguishes its real-physics calculations for gravity, spin, and size from its illustrative towns and landscape. A live panel describes a shell-load estimate, while saved designs remain in the browser and may be lost if site data is cleared.
