Seems to be a pretty big thing these days, along with continuous video of a fireplace and so on. Very soothing; I often put it on the TV in the office when I'm working as watching the scenery come at you is a good way to depressurize every so often.
Update: Need to stop watching this. . . falling asleep.
If this sort of thing interest you, type "Slow TV" into the Netflix search. There's a couple of 8 hour long train rides. Here's one of them off YouTube:
There's a lot of rather long tunnels. And they apparently have no headlights on the engines. Sometimes the screen can be dark for 5-10 minutes while the train goes thru a tunnel.
"slow tv" is also available on the FREE TV app "PLUTO" Can be added to your smart TV or your iPhone , desktop etc.
The train rides are pretty cool from the engineers perspective. Its right above the EyeCandy channel lol
