Well, it looks like floating villas with submerged bedrooms that provide views of the surrounding sea-life off a reclaimed island archipelago shaped like a map of the world in the Persian Gulf.

Along with its Palm Islands, work began on Dubai's The World in the early 2000s. What seemed like ridiculously ambitious projects were, in fact, driven by a need for more real estate, with undeveloped land in the UAE city becoming increasingly rare, and a desire for more beaches.

The World sits 4 km (2.5 mi) off the coast of Dubai. Once complete, the Nakheel development will comprise an archipelago of 300 islands built from dredged sand. Six of those islands make up "Europe" and their owner, the Kleindienst Group, promises that the continent will become a "first of its kind, out-of-this-world island holiday resort."
