This work is one of the works I named the "patapata" series. (Patapata is an onomatopoeic word used in Japan to describe the repetitive motion of a plate-like object.)
In this work, the viewer can move the board freely. In the past, I have attached this board directly to portraits of people, but this time it is a larger version of that.
This work also does not have any useful features. The eerie fascination of repetitive motions, that is all, is the main feature of this work.
