The House of Small Cubes and The Golden Hour (on Netflix, possibly elsewhere) are really good Japanese animated shorts. They're Japanese, but they're not anime — they've got a "drawerly" style rather than a cartoon one.
Hand animation always has these great artifacts that come from lines not being aligned perfectly from frame to frame. The rain in The Golden Hour, for example, looks amazing as a result the line jitters.
They're both stories about moving to a final stage in life. The Golden Hour follows the pattern about a character overcoming self-pity by having to help someone else. That character is an old floor unit TV at the junk yard.
The House of Small Cubes is about an old man who has built new levels onto his house over the years to stay above the rising water levels. Its story pattern is the one about the lone survivor who just has memories left to him.
(I was glad to see it because I t's a lot less bleak than another (non-animated) short I saw a while back, The Phone Call, which was built on the same pattern, in part.)
