A clever optical illusion has gone viral, after claiming to detect stress levels.
The image was created by Japanese neurologist Yamamoto Hashima, and has the ability to seemingly move before your eye.
The original Facebook post reads: "If the image is still, you are calm; if it moves slightly, you are stressed and if it moves like a carousel, you are very stressed."
What do you see?
However, mythbusting site Snopes has now revealed that the image was actually created in 2016 by Mr Perepadia, a 50-year-old designer from Oleksandriya in Ukraine.
Apparently, the image was based on the work of a Japanese psychology professor who specialises in visual illusions and perceptions.
It is also claimed that how you see the image bares no relation to how stressed you are at all, and that Japanese neurologist Yamamoto Hashima doesn't actually exist.
So, there you have it. Still, freaky illusion, right?
