We went to the BFI this weekend for the onedotzero festival. Among a full programme of short Japanese animation films there was this very lovely music video. I looked it up an youtube today and enjoyed it thoroughly again. Do take a look. They have choreographed a charming choreography performed with dozens of people using webcams.
The title of the video is Hibi No Neiro. It is posted on youtube by Masakaaa. According to the info from the onedotzero festival the video is made by Kawamura, Kirkland, Nakamura and Kakamura. Lovely.
