By far the coolest thing I’ve seen on YouTube all week is this Japanese short from 1990. From the video description: “This is not clay animation but gypsum animation. This movie was made by Katushi Bowda. It was broadcast by the Japanese TV program ‘EBITEN’. It was contest for amateur short movie directors. And his present occupation is professional Stop Motion Animator.” More recently, Bowda also created a segment for the feature Winter Days. His website (in Japanese) is Bowdas.com.
