I'm actually a bit surprised that there aren't gopro videos of spectacular hikes that go real time step-by-step from start to finish, that one could use as wallpaper. Wouldn't you want to get one from, let's say, climbing Everest? Or mount one on the nose of a locomotive and film a coast-to-coast train journey?

Not GoPro, but Norwegian broadcaster NRK have filmed several train journeys as part of their "slow tv" offering. Original HD video files (200++ GB) are available [0], and there are multiple versions on Youtube, like a 10 hour trip with Nordlandsbanen from Trondheim to Bodø [1] and a 7 hour trip from Bergen to Oslo [2], including a 10 minute stretch from Finse where the scenes from Hoth in Star Wars Episode V: The Empire Strikes Back were filmed [3].

You can find more videos via searching for the phrase "minutt for minutt" on YouTube.

Those are awesome, and just what I'm talking about. If only there was a wall display!

The video that actually inspired me to go find and hike El Caminito del Rey (back before they renovated it and reopened it)

A friend of mine has brought this to spin class: Scenic cycle - http://sceniccycle.com/

He drove and recorded all the footage himself then opened his studio!

Experienced the projection version of this in an art gallery[1], speaking of flashing.
