This was shown in the background during the segment of the Beatles' 'Ticket to Ride' musical that played the song Blackbird.
It states under the video that this took 50 hours of After Effects work. Dedication. This is good research in terms of how detailed I am to make an animation in 4 - 4.5 weeks with other briefs on top to be doing.
It's a nice animation and a beautiful song. One of my personal Beatles favourites.
