Your brain is the crane operator her🏗️🧠 This crane-and-acorn is a kineticon: a motion illusion made from moving points and lines with very little depth information. Your brain has to guess which side of the crane, hook, and acorn is closer to you. When that guess flips, the rotation can suddenly reverse. Focus on the hook or the hanging acorn. Imagine it moving toward you, then away. Blink, look back, and see if the spin switches 👀🌀 Remember, the direction is built in your mind. #kineticon #
