Oloid

In 1929, Swiss mathematician Paul Schatz discovered an impossible-looking geometric shape: a solid that, when set on a flat surface, rolls in a hypnotic, figure-eight motion — touching every part of its surface as it moves. He called it the Oloid. Nearly a century later, the Oloid is still captivating mathematicians, engineers, and designers alike. Crafted in wood, the Oloid is one of the most quietly mesmerizing objects you can place on a desk — equal parts mathematical curiosity, meditative tool, and sculptural conversation piece.
