@illusionlab_jp: Blink once and this sphere in a cube may spin the other way 👀 HARD TIP: Watch only the far edge. Imagine it's the front. 🧠 Why: a flat picture fits two 3D spins, so your brain has to pick one, and it can switch (kinetic depth effect). How many seconds did it take you to flip the sphere in a cube? ⏱️ Comment your time!
