Miyazaki's Ghibli Museum Commercial
Here is a 2001 commercial for the Ghibli Museum in Mitaka, Japan, animated personally by Hayao Miyazaki. There isn't much else to say, really. It's a very short commercial clip, showing a massively long Cat Bus that feels more like a caterpiller, various characters, and an army of bugs.
If you look carefully, you'll recognize the Radish Spirit from Spirited Away, riding away in the Cat Bus. It's a bit clever, since that character figures in a Totoro riff in Miyazaki's 2001 movie. Bonus points and a cookie to whoever can point it out.
This commercial appears on the Ghibli ga Ippai Special: Short Short DVD in Japan, which belongs in the movie library of all good Ghibli Freaks everywhere.
