The digital windows on
Disney cruise ships was a very popular regular cruise booking category. As I understand the digital window function, they didn't actually have a view to anything but a screen. The screen display was of animated characters and whatever the camera was looking at. The rooms on the starcruiser were similar, but for space travel, planet/system maps and so on. They even displayed jumps to light speed synchronously throughout the "ship." Pretty cool functionality, but perhaps I am easily amused.
