Скачать или смотреть Don't believe your eyes! Is cat spinning clockwise or anticlockwise?

This is an optical illusion caused by a silhouette. The image doesn't have Depth, so your brain (specifically the visual cortex of occipital and parietal lobe) adds the depth arbitrarily. This makes the image move either clockwise or anticlockwise (both are an illusion)

How can you make the cat turn the opposite direction?

1. Unfocus your eyes

2. Look at only one body part - either the cat's arm or tail

3. Now close your eyes, imagine the part spinning the opposite direction (visually push it in the opposite direction)

4. You can also turn the phone horizontally and visualise the spin as up and down, and change that.

This is an exercise to help you realise how hard it is to convince your brain that what you're seeing is not the truth.
