Taking a spin around town

Remember when the cool thing in a big city was a rotating rooftop restaurant? Indianapolis has one, and other cities do, too.

The tiny, but rich, city of Dubai - part of the United Arab Emirates - is going one better: An entire building that rotates. Actually, it's not even the entire building, but each floor can rotate independent of the others.

But what's really cool about this building is that it will use wind and solar power that not only generates enough power for itself, but for 10 surrounding sites.

Dubai is becoming a paradise for architects with some of the most innovate construction projects anywhere. In the process, it's becoming a hot international tourist spot. It's a smart move for a small country to position itself for the future when the oil runs out.
