Developer builds O'Neill cylinder space station sim with Claude
What happened
On October 5, 2026, Hacker News featured a walkable physics simulation of a space station called ISLAND THREE, built by developer @gruberbuilds using Claude. It depicts the cylindrical habitat Gerard K. O'Neill envisioned: 6.4 km in diameter, 32 km long, rotating once every 113.5 seconds at the Earth-Moon L5 point. Sunlight is brought in by mirrors, and "gravity" comes from the station's rotation. The report describes it as a physically accurate O'Neill cylinder simulation.

开发者 @gruberbuilds 用 Claude 打造了名为 ISLAND THREE 的物理模拟空间站，还原 Gerard K. O'Neill 设想：直径 6.4 公里、长 32 公里，每 113.5 秒自转一圈，位于地月 L5 点，阳光来自镜面反射，"重力"来自自转。
