I synchronized the song "Dance of the Sugar Plum Fairy" by Tchaikovsky to a line rider track drawing everything by hand. It took 3 times as much trial and error to make with 3 riders. Huge thanks to David/Conundrumer. He's the software guy who made it possible for me to use multiple riders. Also here is his channel: https://www.youtube.com/user/TheConundrumer It gets a bit crazy to keep track
