You can tell a moving story in a number of different ways through a number of different mediums. None of them are inherently more effective than the other; it’s through the creator’s vision and execution that a truly exceptional piece is defined.
Furiko (Pendulum), an animated film recently featured on Japanese late-night TV program DO! Shinya and later uploaded to YouTube is a perfect example of this, having viewers in tears despite being no longer than 3 minutes.
Even more surprising, this “film” is actually a 1038-page flip book illustrated page-by-page by Japanese comedian Tekken.
