Dubai is becoming the center of the world. It pretty much is (geographicaly). The World Islands will also be an amazing feat. Unfortunately they were having some problems. The reason it was built was because of the clear waters. Because of strong tides they had to create a wall surrounding the Islands, and back a couple months ago it was causing a water circulation problem and it was getting dirty. They deepened the waterways so now hopefully it's all good. The skyscraper was supposed to be smaller than what it's going to be. I think China or someone else was topping their height, so in the middle of construction they decided to add more floors, which was a risky decision, but it's coming along great. You can expect to see many more amazing structures from these people. Dubai is the architect heaven.
