Mathematician and sculptor Kokichi Sugihara recently took to Twitter to post a video of an arrow that cannot point left. No matter how many times the arrow is turned, it simply cannot turn left.

According to a story published in Science Alert, the optical illusion has been taken from a Japanese toy set inspired by Sugihara's mathematical explorations and looks like a simple, white arrow that has been mounted on a wooden stand and points towards the right direction.

However, what has left netizens scratching their heads is the fact that even after swivelling the arrow around 180 degrees, the arrow still keeps pointing towards the right.

Despite being repeatedly swivelled around, it somehow keeps pointing towards the right direction -- every single time.

In the video, the device, one of Sugihara's mathematically designed deceptions; he gives us a glimpse of what is really going on with the arrow, by giving a view from directly above.

From the top view, one can see it is a 3D shaped object, revealing hidden contours that were earlier not visible due to the viewing angle. To heighten the power of its illusionary capabilities, a mirror is introduced which reflects the illusion, once again showing the arrow, this time pointing in the opposite direction.

Needless to say, soon after being posted, the video has gone viral, with over 1.71 million views and over sixty-eight thousand likes.

Here's how people reacted to it:
