The image can appear to move before your eyes and was created by Japanese neurologist Yamamoto Hashima.
You are calm if the image is stationary; you are stressed if it moves little; and you are extremely stressed if it moves like a carousel.
Do you see anything?
The image appears to have been inspired by the research of a Japanese psychology professor who specializes in perceptions and visual illusions.
Additionally, it is claimed that the way you perceive the image has absolutely nothing to do with your level of stress and that the Japanese neurologist Yamamoto Hashima does not actually exist. There you have it, then. Yet another strange illusion, right?
