The Future of Apple's Watch Faces

The environment thing feels very technically complicated like my understanding is it is like a mixture between real imagery and 3d generated stuff. I think they have the ability to do not only like dynamic sounds and stuff in the environment so you got birds just like that it was raining but it definitely wasn't real rain right? The idea here is you kind of close off from the world but you can still have all your windows floating around  and then separately apps can take over the entire interface and do whatever they want.
