This Baffling Optical Illusion Leaves People Scratching Their Heads

Scribbled Arrow

People are puzzled by the spinning arrow that seems to always point right, but it is just a trick for the mind.

Many people shared the trick online. However, people were puzzled at how the arrow could always point in the same direction. You  can see video after skipping few slides.

It is cleverly an optical illusion, invented by Kokichi Sugihara, Meiji University, Japan.

The white arrow was built by Mr. Sugihara, who knew its duplicitous results could only be seen from the top.

This striking illusion is created by thoughtful reflection, perspective, and viewing angle.

The arrow's workings are only revealed at the end of the video when it is compared against a mirror.
