"Fruhtrunk's works are characterized by clear lines, geometric shapes and high-contrast colors. Like almost no other artist of his time, he developed his own abstract visual language with great precision and fascinating perseverance, which he perfected in many variations over the years. By using mathematical methods such as geometric calculations and ratio equations, he created optical illusions and a sense of movement, vibration and flickering in his works. The result is enormously condensed, luminous images that defy passive observation and constantly challenge the visual process. It is not least this visual language that makes the work highly topical." (Kunstmuseum Bonn, retrospective).
