Untitled 

"Untitled," by German artist Gunter Fruhtrunk (1923-1982), is an abstract painting characterized by a rhythmic repetition of vertical red, green, and black stripes. The artist's precise, geometric style, typical of the Op art movement, creates a mesmerizing optical effect that is both playful and dynamic. The stripes seem to oscillate and shift as the viewer's eye moves across the canvas, creating a sense of depth and movement within a flat surface. Fruhtrunk's mastery of color and form in this work is a testament to his ability to captivate the viewer with the interplay of light and illusion.
