Very cool project. I love the tour aspect of it!

I first saw Paris from inside the room, and only later realized that 90% of the cities seem to be outdoors. It did make me kind of miss the indoor theming of the local area.

Also make me think how cool it would be to be able to toggle between being indoors or on the balcony. Shift the volume of the music vs the weather, maybe add some city sounds and shift them as well. Finally, it means you could have twice as much visual variety for only 50% more art.
