So this scene is credited to Miyo Sato as "Paint On Glass" animation. She's a young director and animator who recently graduated from the Tokyo University of Arts Graduate program. Her first year work in the program is a 3 minute short animated this way, its kind of crazy: https://www.youtube.com/watch?v=hOGdWCl0rNQ

Don't be surprised to see more young talent or alternate styles on this project.
