The MM in the picture, do you see her spinning clockwise or counterclockwise?
If you see her spinning clockwise, it indicates that your right brain is more developed than your left brain.
If you see her spinning counterclockwise, it indicates that your left brain is more developed than your right brain.
If you can make her spin clockwise when you want her to spin clockwise, and counterclockwise when you want her to spin counterclockwise, then your IQ is above 160.
Of course, all of these are nonsense, but the picture is indeed very interesting.
The first one is normal, the second one is slowed down. If you can't see any difference in the first one, you can try looking at the second one.
