calm woman angry man illusion!
Mr. Angry and Mrs. Calm Optical Illusion
If you look at the above image from your seat you will see, Mr. Angry is on the left, and Ms.Calm is on the right side ..... but, if you stand-up from your seat, and move back (approx 10 feet away from your computer) you will surprised that Mr. Angry and Ms.Calm switch their places.
BTW, this angry vs happy scary optical illusion is also known as Dr Angry and Mr Calm illusion or Dr Angry and Mrs Calm illusion.
