“kotoni hitoni shirarenumono” means the things that is slipped one’s mind. It is an installation in which crystal balls are secretly drifting in the tea room.
By rotating the suspended wire at a high speed, the crystal ball tied to the wire floats low on the the floor level like a buoy floating in the sea.
The wire disappears depending on how the light is shedded, and it looks like only a crystal ball drifts in the tea room.
The crystal ball that keeps floating in the tea room and the small rotational noise of the wire generated by air resistance reminds somehow a existence of live in the space.
