A dynamic composition of undulating diagonal stripes in warm and cool tones, this screenprint exemplifies Bridget Riley's mastery of Op Art, creating a powerful sense of movement and visual vibration across the surface of the paper. The rhythmic interplay of color and form generates an almost hallucinatory optical effect, drawing the viewer's eye in continuous motion. Created in 2009, the work reflects Riley's enduring exploration of perception and the ways in which pure abstract pattern can produce an intense physiological response in the viewer.
