Every structure a rising civilization builds on its way up the Kardashev scale — from the first satellite belts around a planet to a Dyson sphere swallowing a star — each one rendered in interactive 3D. Pick one to fly in.
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.
