"The Sky-Colored Seed" (Sora Iro no Tane) was a 1992 short film created by Yoshifumi Kondo for Studio Ghibli, broadcast on Japanese network NHK to commemorate their 40th anniversary. This film, the second directed by Kondo (the first being Telecom's 1984 Nemo pilot).
This short film is composed of two segments, and run roughly 90 seconds in all. It's based on a children's book by Reiko Nakagawa and Yuriko Omura. In the story, a boy with a toy airplane meets a fox carrying a seed. The two agree to exchange, and the boy plants the seed into the ground, which grows into a large house that draws together all the animals of the neighborhood. The fox returns, and in his jealousy, demands the return of his seed for the boy's toy plane, and expels all the animals from the house. The house continues to balloon in size, until it pops against the sun, evaporating instantly. The fox is left alone, bewildered.
It's a great little film, cheerfully animated and rendered in that "children's storybook" style. Here is a good example of Studio Ghibli demonstrating their skills, moving beyond the typical "anime" look. Their strong Western influence and willingness to experiment visually has always been the studio's greatest strengths. You never quite knew what to expect from Studio Ghibli. They were always coming up with surprises.
It's hard to realize that we've been without Yoshifumi Kondo for almost 20 years. His loss, in my opinion, proved crippling to Studio Ghibli. I can't say whether he could have crafted an endless supply of blockbuster hits, ala Hayao Miyazaki's blockbuster period, but any new Kondo film would be wonderful, unique, peaceful, humane. The world needs more artists like that, and more charming little movies like The Sky-Colored Seed.
