Toy World Carole Towne Collection

This runs on straight AC power (no batteries, unlike a lot of kids' items). It can run silent, or with sound, and the volume can be adjusted. It always says the same thing though "Come and see the most amazing toys in all the world!" with some other tooty Christmas sounds and mechanical noises, as if by Santa's workshop or something. The pieces move around and parts of it light up. My kids love to turn it on and just watch it for long periods of time, probably because there's so much to see in this one, all packed into a small space. The level of detail is kind of impressive too. You can see lights through a couple of (opaque) windows, and in one spot on the right, you can even see into a living room, with some furniture and a fireplace IIRC (and big teddy bears).
