Twistball consists of 20 curved plastic pieces of which 12 are leaf-shaped and 8 triangular. Together they form a perfectly round colorful ball.All pieces have rounded edges and are made of plastic mass. The leaf-shaped ones have dented edges, while the triangular ones are tipped, and together they comprise a perfect ball – Twistball. One triangle and three leaves comprise a calotte that can be rotated and since the calottes are overlapping by turning one of them you also affect three adjacent ones. Designed by Josip Matijek.
