These polka-dot-covered tree trunks that lined Singapore's Orchard Road for its Biennale in 2006 were by Japanese artist Yayoi Kusama. Kusama began hallucinating dots, nets, and flowers in childhood and now lives in a mental hospital in Tokyo. She often works with polka dots and has said, "...a polka-dot has the form of the sun, which is a symbol of the energy of the whole world and our living life, and also the form of the moon, which is calm. Round, soft, colorful, senseless and unknowing. Polka-dots become movement... Polka dots are a way to infinity." Kusama was interviewed for BOMB in 1999.
