Its a story animation with music. Seems to work well now in the latest Scratch (It seemed to stutter on the Scratch 2.0.) (I made this in Scratch 1.4 a long time ago offline)
Thanks to TheNintendoFan2020 for posting the youtube link to the original car commercial I heard the music for: https://www.youtube.com/watch?v=DcfW_hlYZ5k I saw some jet airliners in the air. I watched them slowly cross the sky. I was thinking about how to fade the contrails and how to have sound like the jets, its always a bit slower... like the sound is a few miles back. But... I got interested in the road and the dividing line, and the trees... so I synched these with another song - sort of similar to a hamlet project i made ( not thematically - just timing)
