DescriptionDyson rings.PNG	Dyson rings forming a stable Dyson swarm, but making it look as similar to a Dyson sphere and Niven ring as possible. Individual objects are unrealistically large to show their shape. Each ring can be replaced by multiple rings in this way (see also). For a stable orbit a ring can be of individual objects, or like this to save on thrusters:

And I do not want to see any discussion about how many light a swarm can catch, at least this image suggests all.
