Dubai has been one of the most exciting and volatile economic stories of the 21st century.

It's global, glitzy, and growing like crazy.

It also has a red-hot property market that has experts warning of a collapsing bubble. Related concerns have been tied to recent crashes in Dubai's stock market.

Still, the tiny economy has developed into a world city that is a business and cultural focal point in the Middle East, and it has the attention of the world.

Tourism and real estate drive the economy, and there seems to be a never-ending development of innovative and over-the-top projects.
