I have two for you. I hope you like them.
Makoto Shinkai's
The Garden of Words is, in a word, exquisite. It is a 46-minute film, very well described in Wikipedia at
film - The Garden of Words .
You are best to watch that film on your best computer. A large screen and fast graphics with good sound. The high-tech nature of the production is demanding. And also, you must be sure to
just keep watching as its credits run down at the end, because that is *not* the end. The film is experimental in its presentation, and you must be sure you have seen it in entirety! A beautiful film: more than beautiful.
Second is a much older film,
The Man Who Planted Trees. Again, Wikipedia tells you lots about it
film - The Man Who Planted Trees . TPB may have a 30m:07s version from the Canadian Broadcasting Corporation, with good video clarity. As the animations are shown as sketches, you want to see them well.
These films are both works of art; both lovely tales for sensitive folk.
