From the Dictionary 4, from the series Rainbow Passes Slowly

This arrangement of geometric forms defined in bands of color creates a startling optical experience. Ay-O’s joyous “rainbow” works were actually borne out of the artist’s apathy for painting. Rather than generating his own subject matter, he appropriated images from fine art and popular culture and reworked them methodically in stripes of color transitioning through the spectrum. Ay-O (the artistic name of Iijima Takao) was a founding member of the avant-garde Fluxus group, a collective of artists, designers, poets, musicians, and dancers. Ay-O became internationally known as the “Rainbow Man” after representing Japan at the Venice Biennale in 1966.
