I bumped into japanese artist Yayoi Kusama work when I was in London a few months ago, she had a great exhibition at Hayward Gallery, where Kusama's dots spread contagiously over every inch of an entire gallery before spilling out to the balcony. Even the trees on the South Bank have come out in spots. Kusama had been a pioneer of Sixties happenings, of polka-dot parades against Vietnam and she was an influence on Claes Oldenburg and Andy Warhol.
She works on feminist, minimalist, surrealist, Art Brut and pop art, all filled with obsession with repetition, pattern, and accumulation coming from a mental illness she struggled with for all her life.
