As the alien structure slowly rotated in the void, each new face it presented seemed entirely different, even after it had made what must have been a complete rotation.

The entire structure rotates with a period of 10h 39m 24s (the same period as that of the planet's radio emissions) which is assumed to be equal to the period of rotation of Saturn's interior.

The structure physically rotates to track the sun, which allows it to harness the maximum natural sunlight and warmth possible.

These structures would rotate at different rates of speed.

An innate structure in the input navigator rotated the orphan's angle of view straight toward the icon.

The near side would be getting nearly three times as much sunlight as the far side, and the structure rotated in seven and a half thirty-hour days.

To allow ships to pass, the whole structure, both arch and road-deck, rotate on huge bearings at either end so that the road deck is lifted.

The structure of the Eads turret extended down to be bottom of the ship and the entire structure rotated.

A disk radiating water jets from its edge creates an image of the sun's rays, and the whole structure rotates about a vertical axis so that the direction in which the "sun" faces is constantly changing.

These provide structure for the other pieces to fit into and rotate around.
