An erroneous analysis of whether this woman turns counterclockwise or clockwise.

I feel clockwise for a while and counterclockwise for a while, which is very high-tech. Anyway, I've been bored with mushrooms at home recently, and this stupid computer can't play games. I can only surf the internet every day, so I decided to import this GIF into Flash and open it. ..... and made the following little animation (see? I can also do flash ~ hum): (Click that "move" and it will move, and it will be obedient. Click "Play Back" to play again. ) By observing this coquettish flash, I think I have found the answer. Judging whether this woman rotates counterclockwise or clockwise depends on: When you see the first frame, do you think this woman is facing you? Or should I turn my back on you? This is the picture below: If you think her back is to you, that is, her left and right sides are the same as yours, her foot is her left foot: (Can you see it is a ponytail? = =) Then you will feel that she is rotating clockwise. ..... If you feel that she is facing you, that is, her left and right sides are opposite to yours, then stand on your right foot: (Sorry! I use a drawing tool) and then you will feel her spinning counterclockwise. The reflection of this woman is counterclockwise, so there is no suspense. So if you always think that she is turning clockwise, then stare at her shadow first ... According to the common sense that the shadow will move in sync with the subject, the brain will arrogantly deduce that "then the subject is also moving in sync with the shadow". Then you will feel that this woman is also turning counterclockwise. ..... I don't know if I can express it clearly, but I'm really not fit to talk about such high-tech things.
