My idea is to create a game by occupying a certain space. In this case, I present a giant version of the classic children’s game in which a marble hits percussion instruments placed on the road at the same time as the marble generates noise by passing over different surfaces. In this installation, any member of the audience can play the role of a performer by moving some of the instruments that are placed there. I would like to dedicate it to Ensemble Researche, who trusted me for the first attempt of the Kugelbahn at the Games as Critical festival.
