Yayoi Kusama lives in a psychiatric institution, which she entered voluntarily in 1977. She is now in her nineties and still works every single day. Known for her repeated dot patterns, her work has been marked with obsessiveness and a desire to escape from trauma. In this video, I show that despite her quirky personality and her status as the most popular artist in the world, she is one of the most radical artists of all time. This is not a film about a specific artwork. This is a film about the simple polka dot. A dot that has obsessed Kusama for nine decades, from her struggle for recognition, to her later years as an art world sensation.
