Haha! That's my video. I thought it was pretty cool when I was there. I think they started that around 9pm, with a DJ on the stage. The fountain wasn't programmed with the music, but there were people in the control booth at the time.
I really have no idea if this is even possible, but I got the impression that they were sort of controlling it on the spot... like parts *did go with the music, and there would be big gaps where it wasn't doing anything, even in the middle of songs. Definitely wasn't the regular programs. Of course, I'm probably wrong, since I know nothing about the tech aspects of the fountain.
