Yayoi Kusama has been working out her obsession with polka dots and infinity over a decades long career. Suffering from hallucinations and residing in a Japanese psychiatric institution, she uses art as a way to communicate her visions. For her current retrospective at the Tate Modern she has created Filled with the Brilliance of Life, her largest infinity room yet. Made up of hundreds of lights and mirrors, it must be dazzling to see in person. It will be on display through June 5.
