Previously watched 5 Centimeters Per Second (Byōsoku Go Senchimētoru) by Makoto Shinkai and loved the way the piece was portrayed. Was on a SQ flight back from Peru, and during the trip, had to watch loads of movies before we touched down. I saw the description on this anime, mentioning the director of 5 Centimeters Per Second. Interesting anime, if you have the time.
Couldn't find a subbed version but this is the video in jap.
