(spinning dancer by Nobuyuki Kayahara)
I had never seen this one before.
Which way does the girl turn when you watch?
Some people believe it depends how your brain works as to which way she spins.
Our youngest can even make her turn at will!
Keep watching, if the direction doesn't change after a while, try looking from the side of the screen.
Our girls loved this and we also looked at lots more optical illusions too.
Please leave comments on this post especially if you have any knowledge of how your brain interprets this and if it is right brain-left brain or some other brain that controls it!!
