Blue Line Optical Illusion Waves

an abstract optical illusion artwork featuring vertical blue lines on a white background. the lines are not perfectly straight; they undulate and curve in a way that creates the impression of a hidden image. some areas of the background show wider expanses of white, while in other areas, the blue lines are more densely packed. the curves and varying thickness of the blue lines form a wavy pattern across the entire composition, contributing to the optical effect. --ar 9:16 --hd
