The Bernal Sphere design is very similar to that used in the science fiction series Babylon 5, although the original Bernal Sphere design is much smaller, only 1 mile in circumference, and can house 10,000 people. Click here for a more detailed description of the Bernal Sphere.

Bernal Sphere agricultural rings seen in cross-section. Farming occurs in the upper layers, and animal husbandry in the lower layers where gravity is a little stronger. Painting by Rick Guidice courtesy of NASA.
Bernal Sphere interior, complete with California-style wine and cheese party, and human powered flight in the lower-gravity area near the axis. Painting by Rick Guidice courtesy of NASA.

Bernal Sphere low-gravity recreation area at dusk, protected by netting. Gravity becomes lower as you approach the center, and at the very top are the zero-gravity honeymoon suites. Painting by Don Davis courtesy of L5 News and National Space Society.
