The latest head-scratching viral snap started making rounds on social The latest head-scratching viral snap started making rounds on social media after Swiss photographer, Tiziana Vergari posted the image on her Instagram page. The picture was posted as a contribution to Instagram's weekend hashtag project,  a series where the platform sets a weekly challenge for users around a theme.

Last week's topic, #WHPidentity, asked the Instagram community to share images and video "celebrating individuality."

Vergari's post, however, was an 'optical illusion' where the same faces were seen repeated and gave rise to immense confusion and debate among the social media community.



It seems nobody can agree whether 13, three or two sets of twins are captured in the photograph. Or whether it is something else entirely.

One user left baffled by the photograph resorted to focusing on the little details and posted: "Four, two of the girls have bracelets on plus the eye line is different on two of the girls."

However, using another logic, another user said: "I see 6 girls when you look at the bracelets."

The post has become a viral sensation with over 17, 400 likes since it was uploaded last week and has taken a life of its own.

Meanwhile, Vergari has confirmed that the photograph she took features two sisters looking into a mirror. Despite this, users continue to debate the number of girls and how the "optical illusion" was captured in the first place.

Around the same time last year, the image of a dress went viral on social media and sparked an intense debate between everyone who has seen the dress. While some saw the dress and said it was black and blue, others were convinced it was white and gold.

It seems that this post will continue to attract further comments and disagreement as the debate rages on, even on Twitter.
