    Edit 2: Keep your eyes only on the dark grey side.

    I have actually built this dragon, thanks for the hit of nostalgia. 😊

    Edit: It is probably inspired by the optical illusion you posted, but made actually impossible.

      It’s half a cube (well, the outer walls of one), it’s just rotating the opposite way you first think it is. Not impossible at all, just a fun few moments of confusion until you catch on.

        Light gray side moves through dark grey and vice versa. Rotate the dragon 360 degrees IRL and you will see why this isn’t possible.

        Edit: even if you made the sides at a perfect opaqueness, there is no way it would look like this IRL.

          You’re seeing a cube from above rotating left. That way doesn’t work. If you instead see a cube from underneath rotating right it very much does work.
