Ring/Sphere worlds

[Suicide Junkie]

I imagine if you're building a ringworld or a sphereworld without blowing up all the planets for raw materials, it would be quite easy to make the ringworld out of the orbital plane of the planets.
The planets would then suffer only two periods of solar eclipse per year if they are outside the ring, and none if inside.

The sphereworld could be designed with "windows" to let beams of light shine on the planets beyond.
