1. His obituary in the New York Times, which has a great interactive feature on some of his more popular movies. Highly recommended reading if you haven’t heard of him before.
2. Blogger Makiko Itoh has very kindly translated Satoshi Kon’s last words — a long blog post that he wrote just before he died as a goodbye to his wife, family, colleagues and the world. (She even includes some cultural notes about it here.)

Kon’s goodbye letter to the world made me tear up as I read it. It’s long, but it’s profoundly moving. To the last, Kon was a great artist.
