We're on record as being against naming contests, but this one looks promising.  The Burj Dubai Lake Fountain is basically a pure-play publicity machine.  It's eye candy - being built to get people to come visit. 
This is exactly the sort of thing that a naming contest is made for. 

You can enter the contest here.

Naming contests are great for PR - and this fountain is basically a long-term PR campaign.  They're getting buzz around the world for a (rather sizable) fountain in the middle of a lake that might otherwise be ignored.  The name may or may not get publicity a few months after launch, but the job of the naming contest will have been done.

They certainly wouldn't be getting coverage here without it...
