You may have already heard about The World, a man-made archipelago currently being built off the coast of Dubai. When completed, the grouping of islands will resemble, more or less, the whole world, and each individual island can be privately purchased by a billionaire who wants to live surrounded by other billionaires..
It’s a clever gimmick. But for the truly eccentric billionaire, why stop there? For enough money, you could build your own island in the shape of whatever you want. Here are a couple more island ideas I came up with.

Of course, the same billionaire should also build Gomerp Isle nearby. But no Gilligan’s Isle. That’s too easy.

That’s right, it’s oriented upside-down. It’s sure to disorient pilots flying overhead, and confuse people who come across it on Google Earth.
The idiom-loving billionaire could build islands which spell out the phrase “NO MAN” so that, finally, No Man is an island. The person who made his or her fortune in pancreatic medicine could live on the Islets of Langerhans, in the shape of the human digestive system. Oh, the island-pun possibilities are endless.
