一个崛起中的文明在攀登卡尔达肖夫等级的途中所建造的每一种结构 — 从环绕行星的第一道卫星带，到吞噬一颗恒星的戴森球 — 每一个都以交互式 3D 呈现。选择一个，飞进去看看。
A cable to orbit — no rockets required.
A hard ring the whole planet lives on.
The planet wrapped in its own captured sunlight.
The first ring of machines a civilization hangs in the sky.
Belts of collectors reclaiming the sunlight a planet wastes.
A man-made star, caged and parked in orbit.
A sun-facing collector that beams starlight home.
