If you've ever been in Las Vegas, or know anything about it, you know that the Bellagio has a very large lake in front of it, with "Dancing Waters" fountains that are choreographed to music. It's extremely elaborate, very cool, and most of the displays are at night. In fact, I was under the impression that they were -all- at night, but that's not the case.
Yesterday I was walking back to my hotel, when a display started, but the sun hadn't set yet. It was about a half hour before sunset, and so I was able to take pictures of the display being backlit by the low-angle sun. It was spectacular. This is one of those pictures. It is the cascade of water falling after a large burst from the fountains. At full power, the fountain heads can fire a shot of water at least fifty feet into the air. When they all go off at full power at the same time, it sounds like a gunshot, followed by the huge cascade of water falling back down into the lake.
