Time lapse of a valley with light fading. One of three segments from Intervalometer Experiments (2004).
There does not appear to be any origin to the film visuals, perhaps from YouTube user gg50840 in June 2009. The music comes from saxophonist David Lynch (NOT the famous film director), a song called Awaiting the Dawn from 1998. https://www.discogs.com/release/3969461-David-Lynch-Wandering-Home
