When Carla and I were in New York a couple of weeks ago, our hotel room faced a building that had beautiful colored lights in the windows. I shot a short video of the light show, which you can see here.
By the way, the Tribeca Grand is a great hotel. Our room (an "iStudio" room) had WiFi, a large screen Macintosh, and an iPod loaded with music. It also had two speakers that pumped out white noise, which did a great job of killing the sound that came from the bar below.
