A mind boggling video of an optical illusion involving, apparently, shape shifting objects has been watched more than 2 million times on YouTube as internet users have struggled to solve the puzzle.
The ‘ambiguous cylinder illusion’ was created by artist Kokichi Sugihara from Meiji University in Japan, who was also named as a finalist in the Best Illusion of the Year Contest 2016 for the installation.
The video begins by showing six rectangular prisms, standing upright in front of a mirror but the reflection looking back reveals six cylinders.
