Watch them here. Because you have nothing else to do. And they're pretty. You can also choose which you want to see, if you're picky like that.
"The URL for this data source has now been found in the community. What I’ve done with this page is parse that data and make the list ... of all the videos in the current Apple TV screensaver rotation. You can watch them all above too, streaming directly from Apple’s servers. Just click one one of the links and the movie will start playing.
tvOS currently picks at random1 from this list — you aren’t normally able to choose what video to play. All this page does is grab that data, parse it and display it as a list.
The current set of videos in the list include imagery from China, San Francisco, Hawaii, New York City and London. Interestingly, there are multiple variants for each location as well as separate day and night shots. It seems like the Apple TV will dynamically show a contextually-relevant video for the user’s time of day. It’s also interesting just how many different sequences Apple has for each same location and time.
If Apple adds new videos, this page will automatically update."
I can't stop thinking about this video of how Eminem was discovered by Dr Dre. It's a fantastic 8 minutes. Give it a watch.
