The Dubai Fountain is currently the world's tallest and most expensive, outshining the Bellagio Fountains, also built by WET Design. It consists of "6,600 WET Superlights and 25 color projectors create a visual spectrum of over 1,000 abstract attractions." Video after the break.
The beam of light shining upward from the fountain can be seen from over 20 miles away, and will be visible from space making it the brightest spot in the Middle East, and quite possibly in the entire world.[via JC - TDM]]
