We've seen Masanobu Hiraoka before, talented animation director enrolled in the lines of Je Regarde. With a solid style for frame by frame animation -very hip these days- Masanobu, tells with mutating shrooms and abstract figures done with precise transitions and maskings. Tearing, shredding, stretching, exploding. Liquid like bodies, spongy characters of dim colored pantones. Pure wizardry and dedication.
I say, possibly the most crafted frame by frame animation director out there.
