You can see the entire grand sweep of the curving cities, which occupy one small space in the habitat ring around the planet Abalakin. What's great about this image from concept designer Alexander Preuss is the way he manages to capture the vast distances and strange, bulging infrastructure that would be part of a beautiful, riverside view if you lived in the halo world.
Preuss, who is currently designing book covers for science fiction novels by Gene Wolf and others, says that this picture of the inner life of a halo world is actually a sequel to an image he created of the outside of the halo world a few years ago. He writes:
This time I wanted to show you how this giant ringworld could look from the inside and how a civilisation would live there.
