Vunderink's series "Reef" is a striking example of the artist's exploration of rhythm and repetition. The series features a grid of stripes, arranged alternating horizontally and vertically, creating a dynamic interplay of lines and colors. The series takes its name from the natural form of a coral reef, and is a nod to Piet Mondrian's painting "Pier and Ocean," which served as a significant influence on Vunderink's work.

Like Mondrian's painting, "Reef" emphasizes the interplay of horizontal and vertical lines to create a sense of movement and rhythm. However, as every stripe is completely equal and the lines are geometrically straight, every sense or hint of a landscape is gone. This along with Vunderink's use of color and his attention to detail give "Reef" a unique and contemporary character.

"Reef" is a powerful example of Vunderink's mastery of abstract composition, and a testament to the enduring appeal of geometric abstraction in contemporary art. By incorporating the influence of Mondrian's "Pier and Ocean," Vunderink pays homage to the legacy of one of the most influential artists of the 20th century while forging his own unique artistic vision.
