Playing with Space: Yayoi Kusama

Since 1977 Kusama has lived voluntarily in a psychiatric institution, and much of her work has been marked with obsessiveness and a desire to escape from psychological trauma. In an attempt to share her experiences, she creates installations that immerse the viewer in her obsessively charged vision of endless dots and nets or infinitely mirrored space.
