A meticulously constructed relief of painted cardboard, *Modulated Ridges* exemplifies Schoonhoven's signature exploration of light and shadow through precise geometric repetition. Rows of carefully formed ridges create subtle undulations across the surface, their white painted finish allowing natural light to animate the composition with shifting tonal gradations. The artist's own frame reinforces the work's self-contained, meditative quality, emphasizing his commitment to a restrained yet deeply considered visual language.
