Binary Gyro Rings

See https://www.grand-illusions.com/collections/maths-toys/products/binary-gyro-rings Binary Gyro Rings are a deceptively simple mechanical toy that reveals surprising mathematics. Each disc contains 8 nested rings that collapse inward when the disc is spun, dropped, rolled, or flipped. Every ring has 2 coloured faces, and as the rings fall inward one by one they reveal a pattern of colours. Because each ring has 2 possible states, the disc behaves like a small mechanical binary system. With 8 rings there are 2⁸ possible states, which equals 256 unique patterns.
