Paul Booker's *Blue Rectangles: Wave Form* is a meticulously constructed composition in which ink-rendered blue rectangles are arranged across translucent Mylar, secured with steel pins to create a dynamic sense of movement and dimensionality. The interplay between the delicate, luminous surface of the Mylar and the cool precision of the steel pins lends the work a tension between rigidity and fluidity. The repeating rectangular forms undulate across the picture plane, evoking the rhythmic energy of a wave in a language of pure geometry.
